Java, square a number

I am working on a basic assignment for school, namely to square a number.

And, I have written the following code; 

Scanner scan = new Scanner(System.in);
System.out.print("Write a number: ");
String mataintal = scan.next();
int nr = Integer.parseInt(mataintal);
String.out.println = mataintal * mataintal;

I am attempting to multiply the number I read with my Scanner, is there some easy way I can do that? And display the square of that number?

Solution

  • Yes. Call the method println from System.out (not String.out which doesn't exist), you don't assign a value to it. And you multiply the int you parsed.

    String.out.println = mataintal * mataintal;

    should be

    System.out.println(nr * nr);
