Question

How would I add something to the end of a string, like an integer?

Example:

int i = 0;
String string = Integer.toString(i);
string = string + suffix;

I tried using the plus sign to add the suffix but it didn’t work. Any help?

The code you’ve given will work absolutely fine:

String suffix = "suffix";
int i = 0;
String string = Integer.toString(i);
string = string + suffix;
System.out.println(string); // 0suffix

My guess is that in your real code, you aren’t assigning the result back to the variable. Note that the + operator doesn’t modify the existing string – it creates a new string. So:

String text = "text";
String copy = text;
text = text + "suffix";
System.out.println(copy); // Still just "text"; refers to original string
