输入三个整数x,y,z，请把这三个数由小到大输出。

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner in = new Scanner(System.in);

System.out.print("\n请输入第一个数:");

int x = in.nextInt();

System.out.print("\n请输入第二个数:");

int y = in.nextInt();

System.out.print("\n请输入第三个数:");

int z = in.nextInt();

int[] a = new int[3];

a[0] = x;

a[1] = y;

a[2] = z;

for(int i=0;i<a.length;i++){

for(int j=0;j<a.length;j++){

if(a[i]<a[j]){

int temp = 0;

temp = a[i];

a[i] = a[j];

a[j] = temp;

}

}

}

for(int g = 0;g<a.length;g++){

System.out.println("g="+a[g]);

}
