Java error missing return statement are those error in Java that occurred
when a programmer forget to write a return statement inside the conditional clauses. method
with a non-void return provides you an object of the specific type.
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);
}
}
