    Default Star Loop

    import java.util.Scanner;
     
     
    public class loops {
    	public static void main(String[] args) {
    	 int length;
    	 int width;
    	int count = 0;			
    	Scanner input = new Scanner (System.in);
    System.out.print("Enter the length: ");
    length = input.nextInt();
    while (length<=0 || length >=21 ) {
    	System.out.print("Invalid – enter length between 1 and 20:");
    	System.out.print("\nEnter the length: ");
    	length = input.nextInt();
     
    }
    System.out.print("Enter the width: ");
     
    	width = input.nextInt();
     
    while (width<=0 || width >=21 ) {
    	System.out.print("Invalid – enter width between 1 and 20:");
    	System.out.print("\nEnter the width: ");
    	width = input.nextInt();
    	if (width>=1 || width <=20){
    		while (count<width){
    			System.out.print("*"); 
    			count++;}
    	 }
    	}
     
     
    	while (count<length){
    		System.out.print("\n*" + width); 
    		count++;}
     
     
    }
     
    }

    Hi how do i solve this. to make my answer equal to the length and width I inputted.

    example:

    Enter the length: 6
    Enter the width: 4
    ****
    ****
    ****
    ****
    ****
    ****

    I always get the length right, but I can't make the width working

    Default Re: Star Loop

    try using 2 different variables for length and width..
    good advice is to debug it, and trace what's happening.
