Java-两个数组合并，并排序打印

有两个数组: 数组a:{7,12,4,9,6,3,9} 数组b:{2,6,3,54,2,56,21,33} 将两个数组合并为数组c,排序打印输出

代码如下：

package com.homework.lhh;

import java.util.Arrays;

public class Ex15 {
    public static void main(String[] args) {
        int[] a = { 7, 12, 4, 9, 6, 3, 9 };
        int[] b = { 2, 6, 3, 54, 2, 56, 21, 33 };
        int[] c = new int[a.length + b.length];
        // 分别输出数组a和数组b
        System.out.print("数组a为：");
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i] + " ");
        }
        System.out.println();
        System.out.print("数组b为：");
        for (int i = 0; i < b.length; i++) {
            System.out.print(b[i] + " ");
        }
        System.out.println();
        for (int i = 0; i < a.length; i++) {
            c[i] = a[i];
        }
        int n = 0;
        for (int i = a.length; i < c.length; i++) {
            c[i] = b[n];
            n++;
        }
        System.out.print("数组c为(数组a+数组b并且升序打印)：");
        Arrays.sort(c);
        for (int i = 0; i < c.length; i++) {
            System.out.print(c[i] + " ");
        }
    }
}

运行结果如图：
