要求说明：
输入三个整数x,y,z，请把这三个数由小到大输出。
实现代码：
第1种方法：
import java.util.Scanner; public class xyzMaxMin{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("请输入3个整数："); int x = sc.nextInt(); int y = sc.nextInt(); int z = sc.nextInt(); System.out.println("从小到大排序后的结果："); if (x < y && x < z) { if (y < z) { System.out.println(x + "<" + y + "<" + z); } else { System.out.println(x + "<" + z + "<" + y); } } else if (y < x && y < z) { if (x < z) { System.out.println(y + "<" + x + "<" + z); } else { System.out.println(y + "<" + z + "<" + x); } } else { if (x < y) { System.out.println(z + "<" + x + "<" + y); } else { System.out.println(z + "<" + y + "<" + x); } } } }
第2种方法：
import java.util.Scanner; public class xyzMaxMin{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("请输入3个整数："); int x = sc.nextInt(); int y = sc.nextInt(); int z = sc.nextInt(); int i = 0; if(x>y){ i=y; y=x; x=i; } if(x>z){ i=z; z=x; x=i; } if(y>z){ i=z; z=y; y=i; } System.out.println("从小到大排序后的结果："); System.out.println(x+"<"+y+"<"+z); } }
第3种方法：
import java.util.Arrays; import java.util.Scanner; public class xyzMaxMin{ public static void main(String[] args) { int[] num = new int[3]; Scanner sc = new Scanner(System.in); System.out.println("请输入3个整数："); num[0] = sc.nextInt(); num[1] = sc.nextInt(); num[2] = sc.nextInt(); Arrays.sort(num); System.out.println("从小到大排序后的结果："); for (int i = 0; i < num.length; i++) { System.out.print(num[i]+"\t"); } } }
