Square/cube root

[tracy22]

How do I allow a user to input a number and then make them select the number 1 to cube or number 2 to square it and produce the result? I don't want to use the math function but rather something like this to square it:
result = var * 2;
System.out.println(result);
Any help in starting would be appreciated

Hi tracy22... Welcome to the forums...

This is an untested code for finding the squares and cubes:

public class myJavaProgram {
  public static void main(String[] args) {
    
    //read the number from the user and store it in variables. Here, I have hardcoded the values
    int num1 = 2;
    int num2 = 100;
    
    //calculating the Sqaure and Cube
    int ResultSquare=num1*num1;
    int ResultCube=num2*num2*num2;
    
    System.out.println("Square :" + ResultSquare);
    System.out.println("Cube :" + ResultSquare);
  }
}

Ah! You are asking for square root and cube roots ? I think, I read the question wrongly.

Then try these links:

Here you go mate.

Math.sqrt()

and

Math.cbrt()

ex.

public class apples {
	public static void main(String args[]){
		System.out.println(Math.sqrt(100));
		
	}
}

Which would print out 10.0

Just realized you were not asking for the root. lol

Since you were explicitly not asking for the Math functions ...
I guess you might be looking for an operator, in which case I have to disappoint you. Java has no power operator as is available in other languages, such as in C#.
