How do I convert from int to String in Java?

To convert an int to a String in Java, you can use the Integer.toString() method. For example:

int x = 42;
String s = Integer.toString(x);

Alternatively, you can use the String.valueOf() method. For primitive int values, it behaves identically to Integer.toString():

int x = 42;
String s = String.valueOf(x);

You can also use the + operator to concatenate an int with an empty string, which will cause the int to be converted to a String:

int x = 42;
String s = "" + x;

Finally, you can use String.format() for formatted conversion:

int x = 42;
String s = String.format("%d", x);
