Creating Method
What will be the output of the following program?
public class FindOutput
{
    public static void main(String args[])
    {
        int a = 5;
        System.out.println(cube(a));
    }
    int cube(int theNum)
    {
        return theNum * theNum * theNum;
    }
}

A. 125
B. Compilation Error because cube is already defined in the java.lang.Math class.
C. Throws an arithmetic exception.
D. Compilation Error or Runtime Error for some other reason.

User comments below. All of them might not be correct.

Ans is D.
In the program the method cube() is a non-static method which cannot be accessed directly in the static context... If we want to call a non-static method then we have to create an object of the class and on that class we need to call that method.. If we call a non-static method from the static field directly then it will raise a compile-time error...

ANS is D

--Here,the cube() method is defined in class which is non-static and main is static.

--After that a is assigned 5.inside cube() method cube of a number is found out and returned to main method().

--But the rule says,static method can access only static methods and variables only.

Here cube is non-static method and it is called in main().so it will throw compilation error.
