Quiz on methods

What will be the output of the following program?

public class Madam

{

public static void main(String[] args)

{

int a = 5;

System.out.println(cube(a));

}

static int cube(int theNum)

{

return theNum * theNum * theNum;

}

}

• Throws an ArithmeticException.

• 125

• Compilation Error or Runtime Error for some other reason.

• Compilation Error because cube is already defined in the java.lang.Math class.

What will be the output of the following program?

class Equation1

{

public static void main(String s[])

{

int x = 6;

int y = 3;

int z = 12;

int w = method1(x, y, z);

System.out.println("w = " + w);

}

public static int method1(int y, int z, int x)

{

return (x * z) / y;

}

}

• w = 24

• Compilation Error

• w = 36

• w = 6

What will be the output of the following program.

class MethodsTest

{

public static void main(String s[])

{

int a = 34;

int b = 56;

int c = 0;

sum(a, b);

System.out.println("c = " + c);

}

public static int sum(int a, int b)

{

System.out.println("a = " + a + " b = " + b);

int c = 0;

c = a + b;

System.out.println("c = " + c);

return c;

}

}

• a = 34 b = 56

  c = 90

  c = 90

• a = 34 b = 56

  c = 90

  c = 0

• a = 34 b = 56

  c = 0

  c = 0

• Compilation Error

What is the output of the following program?

{

Test obj = new Test(); System.out.println(obj.getData());

} }

• 1

• 0

• Runtime error

}

public static void main(String[] args)

{

Test obj = new Test();

System.out.println(obj.function());

}

}

• Compilation error

• Runtime error

• GFG

• None of these

What is the output of the following program?

}

public static void main(String[] args)

{

Test obj = new Test();

System.out.println(obj.function(1., 20));

}

}

• GFG

• Compilation error

• Runtime error

• GeeksforGeeks
