Return Values

Java Return

In the previous sections, we used the void keyword in all examples, which indicates that the method should not return a value.

If you want the method to return a value, you can use a primitive data type (such as int, char, etc.) instead of void, and use the return keyword inside the method:

Example

public class Main {
  static int myMethod(int x) {
    return 5 + x;
  }
 
  public static void main(String[] args) {
    System.out.println(myMethod(3));
  }
}

Output:

This example returns the sum of a method's two parameters:

Example

public class Main {
  static int myMethod(int x, int y) {
    return x + y;
  }
 
  public static void main(String[] args) {
    System.out.println(myMethod(5, 3));
  }
}

Output:

You can also store the result in a variable (recommended, as it is easier to read and maintain):

Example

public class Main {
  static int myMethod(int x, int y) {
    return x + y;
  }
 
  public static void main(String[] args) {
    int z = myMethod(5, 3);
    System.out.println(z);
  }
}

Output:
