It's so weird that the String + operation has a bug:
String path = "/app/" + monPHost.getUsername() + "/app/" + monProcessInfo.getRegion() + "/tf/bin";
System.out.println("here it ...." + path);
This is the result:
here it ..../app/aiams/app/791
Where has the "/tf/bin" gone?
Maybe monProcessInfo.getRegion() is ending with a carriage return. Try to pre-process it, strip it, and the concatenate with your string.
OR, try this:
String path = "/app/" + monPHost.getUsername() + "/app/" + monProcessInfo.getRegion();
path = path + "/tf/bin";
System.out.println("here it ...." + path);
As a quick work around for all the spaces you're getting:
String path = "/app/" + monPHost.getUsername() + "/app/" + monProcessInfo.getRegion().trim() + "/tf/bin";
System.out.println("here it ...." + path);
I recommend tracking this down in your process object and fixing it there, if you only ever expect an Integer result try to return one, failing fast & early can prevent a lot of downstream bugs.
Given in comment you mentioned monProcessInfo.getRegion() is giving you a String with lots of spaces, and you haven't mentioned the type of return for this method, here is what you may do:
If it is returning a String:
It will be as easy as
String path = "...." + monProcessInfo.getRegion().trim() + "/tf/bin";
If it is returning something else:
Given String concat in Java is relying on Object.toString(), you can change it to:
String path = "...." + monProcessInfo.getRegion().toString().trim() + "/tf/bin";
Since you mentioned that monProcessInfo.getRegion() returns lots of spaces, you can try trimming it before appending it to the later part of the string.
StringBuilder sb = new StringBuilder();
sb.append("/app/" + monPHost.getUsername() + "/app/");
String region = ("" + monProcessInfo.getRegion()).trim();
sb.append(region + "/tf/bin");
System.out.println("here it ...." + sb.toString());

I am using a .csv file and would like to pass a string constructed by a function to: parserSettings.selectFields( function );
During testing, when the string returned by the function is pasted directly into: parserSettings.selectFields( string ); the parsing works fine, however, when the function is used instead, the parse doesn't work, and there is only output of whitespace.
Here is the function:
public String buildColList() {
//Parse the qty col names string, which is a comma separated string
String qtyString = getQtyString();
List<String> qtyCols = Arrays.asList(qtyString.split("\\s*,\\s*"));
String colString = StringUtils.join(qtyCols.toArray(), "\"" + ", " + "\"");
String fullColString;
fullColString = "\"" + getString1() + "\"" + ", " + "\"" + getString2() + "\"" + ", " + "\"" + colString + "\"" + ", " + "\"" + getString4 + "\"";
return fullColString;
}
Here is how it is placed:
parserSettings.selectFields(buildColList());
Any help would be greatly appreciated, thanks.
You need to return an array from your buildColList method, as the parserSettings.selectFields() method won't split a single string. Your current implementation is selecting a single, big header instead of multiple columns. Change your method to do something like this:
public String[] buildColList() {
//Parse the qty col names string, which is a comma separated string
String qtyString = getQtyString();
List<String> qtyCols = Arrays.asList(qtyString.split("\\s*,\\s*"));
String colString = StringUtils.join(qtyCols.toArray(), "\"" + ", " + "\"");
String[] fullColString = new String[]{getString1(), getString2(), colString, getString4};
return fullColString;
}
And it should work. You might need to adjust my solution to fit your particular scenario as I didn't run this code. Also, I'm not sure why you were appending quotes around the column names, so I removed them.
Hope this helps.
I have a string from which I need to remove all mentioned punctuations and spaces. My code looks as follows:
String s = "s[film] fever(normal) curse;";
String[] spart = s.split("[,/?:;\\[\\]\"{}()\\-_+*=|<>!`~##$%^&\\s+]");
System.out.println("spart[0]: " + spart[0]);
System.out.println("spart[1]: " + spart[1]);
System.out.println("spart[2]: " + spart[2]);
System.out.println("spart[3]: " + spart[3]);

System.out.println("spart[2]: " + spart[2]);
System.out.println("spart[3]: " + spart[3]);
But, I am getting some elements which are blank. The output is:
spart[0]: s
spart[1]: film
spart[2]:
spart[3]: normal
- is a special character in PHP character classes. For instance, [a-z] matches all chars from a to z inclusive. Note that you've got )-_ in your regex.
- defines a range in regular expressions as used by String.split argument so that needs to be escaped
String[] part = line.toLowerCase().split("[,/?:;\"{}()\\-_+*=|<>!`~##$%^&]");
String[] spart = s.split("[,/?:;\\[\\]\"{}()\\-_+*=|<>!`~##$%^&\\s]+");
Here is my code:
// This is the bug - this works.
String[] lst = {"desk", "pencil"};
String lst0 = lst[0];
System.out.println("path: " + lst[0]);
System.out.println("result: " + root.getDirectory(lst0).getFileName());
// This is the bug - this doesn't work.
String[] ef = "desk/pencil".split("/");
String ef1 = ef[0];
System.out.println("path: " + ef1);
System.out.println("result (without getFileName): " + root.getDirectory(ef1));
But in the second case, the function isn't called properly, as ef[0] seems considered differently from lst[0] by the compiler despite both being strings. I assume this is becaue lst is a array that resulted from list splitting. Is there any way to fix/work around this?
my codes dont seem to properly address what i intend to achieve.
a long string instead of a well broken and seperated string
it does not handle the 'seperator' appropriately ( produces , instead of ",")
also the 'optional' ( produces ' instead of " '")
Current result:
LOAD DATA INFILE 'max.csv'BADFILE 'max.bad'DISCARDFILE
'max.dis' APPEND INTO TABLEADDRESSfields terminated by,optionally enclosed
by'(ID,Name,sex)
the intended result should look like this
is there a better way of doing this or improving the above codes
Yeah. Use the character \n to start a new line in the file, and escape " characters as \". Also, you'll want to add a space after each variable.
content = " LOAD DATA\nINFILE "+ fileName + " BADFILE "+ badName + " DISCARDFILE " +
discardName + "\n\nAPPEND\nINTO TABLE "+ table + "\n fields terminated by \"" + separator
+ "\" optionally enclosed by '" + optional + "'\n (" + column + ")";
This is assuming fileName, badName, and discardName include the quotes around the names.
Don't reinvent the wheel... the apache commons-io library does all that in one line:
FileUtils.write(new File(controlName), content);
Here's the javadoc for FileUtils.write(File, CharSequence):
Writes a CharSequence to a file creating the file if it does not exist
To insert a new line you need to use \n or \r\n for windows
for example
discardName + "\n" //New line here
"APPEND INTO TABLE"
For the double quote symbol on the other hand you need to specifically type \" around the comma:
"fields terminated by \"" + separator +"\""
which will produce this ","
and that is similar to what the optional variable needs to be
Java newbie here, I'm having trouble setting a new line in this code:
String FnameTextboxText = FnameTextbox.getText();
String LastnameTextboxText = LastnameTextbox.getText();
String CourseTextboxText = CourseTextbox.getText();
Summary.setText("Firstname:" + " " + FnameTextboxText + "\nLastname:" + " " + LastnameTextboxText + "\nCourse:" + " " + CourseTextboxText);
Also tried something like: "\n" + "Lastname" But its no good.
Do you have any idea on how to make new lines. So that it'll look like this;
Firstname: x
Lastname: y
Course: Z
Using netbeans 6.8. On windows.
I guess you need to use TextArea.
First, use TextArea
Second, test using \r or \n or \r\n
Sometimes, people use \n to make new line and sometimes, like me, use \r\n to make new line
