Java error missing return statement

Understand with Example

In this Example we want to describe you a code that explain you in understanding Java error missing return object. For this we have taken a non void method 'operation( )'that return you an int type and this method include a for loop clause that check the condition If there is anything other than void method, then you must specify the return type in it. The given below code is missing a return statement in the non-void method so, whenever the compiler execute the code the code returns a missing return statement error.

There are two way to resolve this problem-

1)Change the non-void method to a void method.

2)Add or write a return expression to the non-void method.

Missingreturnstatement.java

public class Missingreturnstatement {

  public int operation(int num) {
  for (int i = 0; i <= num; i++) {
  System.out.println(i);
  }

  }

  public static void main(String[] args) {
  Missingreturnstatement m = new Missingreturnstatement();
  m.operation(7);
  }
}
