java比较三个数的大小练习以及代码实例。java习题展示。 java简单的题目：输入三个整数x,y,z，请把这三个数由小到大输出。

import java.util.Scanner;

/*
*/
public class Basic15 {

public static void main(String[] args) {
Basic15 my = new Basic15();
my.go();

}
public void go()
{
System.out.println(“请输入3个整数”);
Scanner sc;
int a=0;
int b=0;
int c=0;
try {
sc = new Scanner(System.in);
a = sc.nextInt();
b = sc.nextInt();
c = sc.nextInt();
} catch (Exception e) {
// TODO Auto-generated catch block
System.out.println(“输入有误”);
go();
}
compare(a, b, c);
go();
}

public void compare(int a,int b,int c)
{
int n1=0;
int n2=0;
int n3=0;
n1=Math.max(c,Math.max(a, b));
n3=Math.min(c,Math.min(a,b));
n2=(a>n3&&a<n1)?a:(b>n3&&b<n1)?b:c;
System.out.println(“由小到大依次为”+n3+” “+n2+” “+n1);
}

}
程序运行结果如下图
