Question

输3个整数，分别赋值给int变量a，b，c，再将输入的整数从小到大的放在变量a，b，c中，并输出三个变量的值

输入3个整数，分别赋值给int变量a，b，c，再将输入的整数从小到大的放在变量a，b，c中，并输出三个变量的值
我刚学java，用的eclipse。。。。前面还好说，就是将输入的数字从小到大放在变量并输出是在是写不出来了。。。。。用什么语句写？boolean？if？帮帮忙吧。。。

Answer 1

import java.util.Scanner;
public class TestForQ {
public static void main(String[] args){
int a = 0;
int b = 0;
int c = 0;
Scanner sc = new Scanner(System.in);
a = sc.nextInt();
b = sc.nextInt();
c = sc.nextInt();
if (a > b) {
int temp = a;
a = b;
b = temp;
}
if (a > c) {
int temp = a;
a = c;
c = temp;
}
if (b > c) {
int temp = b;
b = c;
c = temp;
}
System.out.println("a=" + a);
System.out.println("b=" + b);
System.out.println("c=" + c);
}
}

楼主是三个数的比较吗？
import java.util.Scanner;

public class Demo7 {
public static void main(String[] args) {
int a = 0, b = 0, c = 0;
int[] arr=new int[3];
Scanner s = new Scanner(System.in);
for (int i = 0; i < 3; i++) {
arr[i]=s.nextInt();
}
a=arr[0];
b=arr[1];
c=arr[2];
int max=a;
if(a<b)
max=b;
if(max<c)
max=c;
System.out.println(a+""+b+""+c);
System.out.println(max);
}
}
