太原理工大学java编程题有两个数组:数组a为1,7,9,11,13,15,17,19,数组b为2,4,6,8,

好的，我明白了。针对您的问题，我可以给出以下Java代码实现将两个数组合并并按升序排列的结果：

import java.util.Arrays;

public class MergeArrays {
    public static void main(String[] args) {
        int[] a = {1, 7, 9, 11, 13, 15, 17, 19};
        int[] b = {2, 4, 6, 8};
        int[] c = new int[a.length + b.length];
        System.arraycopy(a, 0, c, 0, a.length);
        System.arraycopy(b, 0, c, a.length, b.length);
        Arrays.sort(c);
        System.out.println(Arrays.toString(c));
    }
}

输出结果为：[1, 2, 4, 6, 7, 8, 9, 11, 13, 15, 17, 19]
