Every Java Class MUST contain the main method: 'public static void main(String[]args)'   true/false

Answer 1

int a = 12; //declaring variable a as integer and initializing it with 12.

a += 3; // a = a + 3 = 12+ 3 = 15.

System.out.println(a); // prints 15 to the console.

So the output of the above code is 15.

new is keyword used in java for creating an object in memory.

For example Car c = new Car() // it will create a car object inside memory.

So the answer is : creates a object in memory.

Answer is false.

Every class in java need not contain main method. In a java file only one class can contain a main method.

So the correct answer is false.
