Question

求编程大佬 谢谢

Answer 1

//2. 分钟换算

int h = 560/60;
int m = 560-60*h;
System.out.println(h+"小时"+m+"分钟");

//3. 个位，十位，百位求和
System.out.println("请输入一个三位数：");
Scanner sc = new Scanner(System.in);
int num = sc.nextInt();
int sum = num%10+num%100/10+num/100;
System.out.println("和是："+sum);

//4. 交换变量

System.out.println("请输入两个变量：");

Scanner scanner = new Scanner(System.in);
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
System.out.println("交换前的顺序为："+num1+" "+num2);
int num3 = num1;
num1 = num2;
num2 = num3;
System.out.println("交换后的顺序为："+num1+" "+num2);
