我不知道我的代码有什么问题

Question

我拿不到输出。。有人能帮我得到输出吗

下面给出了程序运行的示例（注意：下面的粗体文本是用户输入的输入）：

输入三角形的三条边

import java.util.*;

public class right_angle_triangle {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int count = 0;
        char ch = 'y';
        while(ch == 'y'){
        System.out.print("Enter the three sides of a triangle> ");
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
        
        if(a>0 && b>0 && c>0){
            int a1 = a*a;
            int b1 = b*b;
            int c1 = c*c;
            if(c1== a1+b1 || b1==a1+c1 || a1==b1+c1){
                count++;
                System.out.println("Yes, this is a right-angled triangle.");
            }
            else {
                System.out.println("No, this is not a right-angled triangle.");
            }  
        }
        else{
            System.out.print("No, this is not a right-angled triangle.");
        }          
                System.out.print("Do you want to continue? (y/n) > ");
                ch = sc.next().charAt(0);

                
System.out.println("The total number of right-angled triangle = "+count);
            }
            
        }
        
        }

你能解释一下你真正想要的是什么吗？因为我测试过它会打印输出：

Enter the three sides of a triangle> 5
3
4
Yes, this is a right-angled triangle.
Do you want to continue? (y/n) > 

好的，我想，我明白你的情况下有什么问题，你必须按Enter每次给输入。
