Converting String to int in Java?

Integer x = Integer.valueOf(str);
// or
int y = Integer.parseInt(str);

There is a slight difference between these methods:

• valueOf returns a new or cached instance of java.lang.Integer
• parseInt returns primitive int.

To convert a string into an int, use:

String str = "1234";
int num = Integer.parseInt(str);
To convert a number into a string, use:
int num = 1234;
String str = String.valueOf(num);
