Replacing at an index

[bugger]

I am using Strings and want to replace a character at a particular index. How this can be done. I am not able to find the required method.

Thanks.

Code:

		String str = "there are 4 apples";
		int index = 10 ;		
		str = str.substring(0,index) + "5" + str.substring(index+1);
		System.out.println(str);

Why not just use the replace method

Code:

//We want to replace index 1 with the character 'a', so here's what we do
String s = "Hello";
char oldChar = s.charAt(1);  //returns the character at index 1
String newString = s.replace(oldChar, 'a');

This is what you wanted right?
