I'm debugging an application and realized that the debugger displays String[] in two different ways, namely these two: ['test'] and [test]. Those displayed in the second way work for my purpose and the other doesn't.
What's the difference between these two?
It sounds like in the first case, the single quote characters are part of the string. Try adding code to remove them.

I'm writing a simple program where I can change a piece of text. For example printing text "This is a problem with xxx" and I could delete "xxx" and place my own text there. "xxx" representing a default value.
I tried searching but I think I'm using the wrong search terms or I just don't understand the answers.

Is there a way to clear multiple lines of text printed in the console with Java?
I'm trying to print 2 pictures made with text that are slightly different and replace each other in a loop. Thus, I want to print a multiline string and then clear the screen before printing the next string. However, I don't know how to clear the screen.
I've already tried using \r, but that doesn't work because it's multiple lines.
u/sellithy on reddit helped me out with this link
and the block of code that worked for me was
System.out.print("\033[H\033[2J");
System.out.flush();

So the question is basically if to have
getDriver().findElement(by).clear();
or to have
String text = getDriver().findElement(by).getText();
if (!text.equals(""))
getDriver().findElement(by).clear();
and after that a sendKeys.
Note: Most of the times, the field is empty.
This is simple math
getDriver().findElement(by).clear();
Costs as
getDriver().findElement(by).getText();
To the second line you add an if check and maybe getDriver().findElement(by).clear(); anyway.
So just call clear() without a check.

I have this code in Python:
if word[x:x+2] in twowords:
(twowords is a list). I can't figure out how to write in twowords in Java.
It looks like Python uses [x:y] to create a substring. You can use the substring method for that purpose, with the same parameters.
There is no in syntax in Java, but all Lists in Java support the contains method.
Try
if (twowords.contains(word.substring(x, x+2)))

I'm thinking on possibility of making a Huffman code without "node".
It's based on the nodes then my question seems a bit ambiguous.
I know,maybe we have to use string's abilites ...
Is it possible ? and if "YES" how Is it possible in java?
Thanks.
You can use indices instead of nodes but you need somewhere nodes and/or vertices.
