本文提供了一个使用Java编写的简单程序示例，该程序通过用户输入接收三个整数，并将这三个数按升序排列后输出。程序首先利用Scanner类获取用户输入的三个整数，然后通过一系列条件判断进行数值交换，确保输出的顺序为从小到大的顺序。
public static void test5(){
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = sc.nextInt();
int z = sc.nextInt();
int i = 0;
if(x>y){
i = x;
x = y;
y = i;
}
if(x > z){
i = x;
x = z;
z = i;
}
if(y>z){
i = y;
y = z;
z = i;
}
System.out.println(x+","+y+","+z);
}
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int y = sc.nextInt();
int z = sc.nextInt();
int i = 0;
if(x>y){
i = x;
x = y;
y = i;
}
if(x > z){
i = x;
x = z;
z = i;
}
if(y>z){
i = y;
y = z;
z = i;
}
System.out.println(x+","+y+","+z);
}
