package cn.kgc.demo4;import java.util.Scanner;public class Test { public static void main(String[] args) { Scanner input =new Scanner(System.in); System.out.println("====欢迎您来到宠物店！=====");System.out.println("请输入你要领养的宠物名字：");String petName =input.n

//使用冒泡排序，把数列8，7，9，4，5，6按照升序排序public class Demo13 { public static void main(String[] args) { int [] nums= {8,7,9,4,5,6};int temp;for (int i = 0; i < 5; i++) { for (int j = 0; j < nums.length-1-i; j++) { if (nums[j]>nums[j+1]) { temp=nu

在这里插入import java.util.Scanner;public class Demo1 { public static void main(String[] args) {Scanner input =new Scanner(System.in);int num;do { System.out.println("请你输入菱形的行数："); num =input.nextInt();} while (num%2==0);int shang=num/2+1;int xia=nu

public class Demo1{public static void main(string[] args){for(int i=1;i<=4;i++){for(int j=1;j<=4-i;j++){system.out.print(" ");//-->输出空格}for(int k=1;k<=2i-1;k++){system.out.print("*");}system.out.println();//-->换行}}}...

public class Demo1{public static void main(string[] args){for(i=1;i<=5;i++){for(j=1;j<=5;j++){system.out.print("*")}system.out.println();}}}

// 1*1// 2*1 2*2 // 3*1 3*2 3*3....public class Demo1{public static void main(string[] args){for(int i=1;i<=9;i++){for(int j=1;j<=i,j++){system.out.print(i+"*"+j+"="+(i*j) );}system.out.println() //-->换行}}}
