【程序5】
题目：输入三个整数x,y,z，请把这三个数由小到大输出。

代码实现1：

package p05;

import java.util.Scanner;

public class P05 {
    public static void main(String[] arg){

        System.out.println("请输入x：");
        Scanner scanner = new Scanner(System.in);
        int x = scanner.nextInt();


        System.out.println("请输入y：");
        Scanner scanner1 = new Scanner(System.in);
        int y = scanner.nextInt();

        System.out.println("请输入z：");
        Scanner scanner2 = new Scanner(System.in);
        int z = scanner.nextInt();

        if(x > y ){
            if(y > z){
                System.out.println( z +" "+ y +" " +x);
            }
            else if(y < z){
                if (x > z){
                    System.out.println(y + " " + z + " " + x );
                }
                else
                    System.out.println(y + " " + x + " " + z);
            }

        }
        else if(x < y){
            if(x < z){
                if(y < z){
                    System.out.println(x + " " + y +" " + z);
                }
                else
                    System.out.println(x +" " + z + " " + y);
            }
            else if(x > z){
                System.out.println(z + " " + x + " " + y);
            }
        }


    }

}

运行结果：

代码实现2：

package p005;

import java.util.Scanner;

public class P005 {
    public static void main(String[] arg){
        int min;
        System.out.println("请输入x的值：");
        Scanner scanner = new Scanner(System.in);
        int x = scanner.nextInt();
        min = x;

        System.out.println("请输入y的值：");
        Scanner scanner1 = new Scanner(System.in);
        int y = scanner.nextInt();

        System.out.println("请输入z的值：");
        Scanner scanner2 = new Scanner(System.in);
        int z = scanner.nextInt();

        if(x > y){
            min = y;
            y = x;
            x = min;
        }

        if(y > z){
            min = z;
            z = y;
            y = min;
        }

        if(x > z){
            min = z;
            z = x;
            x = min;
        }

        System.out.println("The sort queue is" + x +" " + y +" " +z);
    }

}

运行结果：

【程序6】
题目：用*号输出字母C的图案。

package p06;

public class P06 {
    public static void main(String[] arg){
        System.out.println("  *****");
        System.out.println(" *");
        System.out.println("*");
        System.out.println(" *");
        System.out.println("  *****");
    }
}

运行结果：
