I have a string String myStringArray = "[491174, 414529, 414557]";. I want output 491174, 414529, 414557 just this part. I tried many methods to convert string to array and many other things. I tried something I'm adding the code below.
My Code
String myStringArray = "[491174, 414529, 414557]";
String newArray = myStringArray.replaceAll(" ", "");
System.out.println("Before Remove : " + newArray);
String remove = newArray.replaceAll("[^a-zA-Z0-9]", ",");
String rm = remove.replaceFirst(",", "");
System.out.println("After Remove : " + rm);
Output
Before Remove : [491174,414529,414557]
After Remove : 491174,414529,414557,
As you can see I have , in the end and I don't know how to remove this ,. Please help me if you can.

rm = rm.substring(0, rm.length() - 1);

How to check the beginning of a string contains a number in Java and convert the same into a number?
String s="-495asadad";

String s="-495asadad";
ParsePosition pp = new ParsePosition(0);
Number num = NumberFormat.getInstance().parse(s, pp);
if (pp.getIndex() == 0) {
System.out.println("No number there");
} else {
System.out.println("Number found: " + num);
}
Output:
Number found: -495
You will probably want to consider more precisely what constitutes a number and from that, how your NumberFormat should work.
The two-arg parse method tries to parse a number from the specified position. In this case position 0, the start of the string. If successful, it will update the position to after the number. If not, it will remain 0, so this is what I test in the if statement.

i want to Detect and put english Sentence in one array and Persian Sentence in another array
How can i do ؟

Assuming all your text is in a file and that English and persian translations are on different lines.
What you need to do is read each line from the file and check if it is ASCII or not.
How do you check that?
import java.nio.charset.Charset;
import java.nio.charset.CharsetEncoder;
public class StringUtils {
static CharsetEncoder asciiEncoder =
Charset.forName("US-ASCII").newEncoder(); // or "ISO-8859-1" for ISO Latin 1
public static boolean isPureAscii(String v) {
return asciiEncoder.canEncode(v);
}
public static void main (String args[])
throws Exception {
String test = " برام ";
System.out.println(test + " isPureAscii() : " + StringUtils.isPureAscii(test));
test = "Real";
System.out.println(test + " isPureAscii() : " + StringUtils.isPureAscii(test));
/*
* output :
* برام isPureAscii() : false
* Real isPureAscii() : true
*/
}
}

I have csv file with below data How I can remove empty rows in java through regex I tried using ^,+$ but Its not working
"Temp-A007","Default","Importing","","",""
"","",""

You can do it through RegEx. Simply use input.replaceAll("(\"\\s*\"\\s*,?)", "");
Output
input : "Temp-A007", "","Default","Importing","","",""
output : "Temp-A007", "Default","Importing",
Code
public class Test {
public static void main(String args[]) {
String input = new String("\"Temp-A007\", \"\",\"Default\",\"Importing\",\"\",\"\",\"\" ");
String output = input.replaceAll("(\"\\s*\"\\s*,?)", "");
System.out.println("input : " + input);
System.out.println("output : " + output);
}
}

An "empty" row will have at most commas, quotes, and spaces, no? How about:
^[", ]*$
?

I would like to know if there is a way to extract verbs from a string.
As an example :
I'll eliminate you.
I want it to only extract "eliminate".

You probably want to be looking at using the Stanford PoS tagger (http://nlp.stanford.edu/software/tagger.shtml). It will tag the string with it's classification (e.g. verb, noun). You can then use a regular expression to pull out the verbs.

ArrayList<String> verbs = new ArrayList<>();
verbs.add("eliminate");
String yourtext = "I'll eliminate you";
for (String verb : verbs) {
int index = yourtext.indexOf(verb);
if (index >= 0) {
System.out.println("Found verb: " + verb + " at position: " + index);
}
}
I'll leave filling the verbs array up to you.
