Is there a substring function (start, length)?

Question

I am trying to use a similar method for C # string.SubString(int start, int length) .

But the subscript function in Java is string.substring(int start, int end) .

I want to be able to pass in the starting position and the length of the subscript function.

Can someone help me solve this problem?

Answer 1

It could be something like

 String mySubString(String myString, int start, int length) { return myString.substring(start, Math.min(start + length, myString.length())); } 

Answer 2

The closest thing you can get is using the String constructor

 new String(input.getBytes(),start,length); 

Answer 3

Yes

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#substring(int , int)

public String substring (int beginIndex, int endIndex)

you just need to calculate a bit to get endIndex.
