    Default I'm new and I'm Stuck

    This might be easy for some of y'all, but I'm very new and I'm stuck. I'm not sure how to get past this.
    public class JavaClass{
             public static void main (String [] args){
     
                System.out.println("Welcome to Matthew Galetti's Rectangle and Square Calculator");
     
                //System.out.println("Rectangle Width Value");
                //int number = 6;
                //System.out.print(number);
     
     
                //System.out.println("Rectangle Length Value");
                //int number2 = 20;
                //System.out.print(number2);
     
     
                System.out.println("The Area of the Rectangle is 120");
                int product = number * number2;
                //20*6=120
                int number = 120;
                System.out.print(product);
     
                System.out.println("The Perimeter of the Rectangle is 52");
                int sum = number + number + number2 + number2;
                //6+6+20+20=52
                int number = 52;
                System.out.print(sum);

    int number = 52;

    5 errors

    all those errors marks are underneath the n's in the N's in the word numbers. When I put it into the post they didn't come out that way.

    JavaClass.java:21: error: cannot find symbol
    int product = number * number2;
    ^
    symbol: variable number
    The compiler can not find a definition for the variable number for the statement on line 21.
    Make sure number is defined before trying to use it.

    The same for the other cannot find symbol errors.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
