What is the difference between int main () and void main()

Answer 1

int main() must return a value, while void main() doesn't return a value.
Example:

public int myMethod() {
int age = 20;
Return age;
}

void Example:

public void myMethod () {
System.out.println("my name is Trevor");
}

You don't have to place a "return" here because the method didn't mention any "int" or "String" type here.
