两升序数组合并成一个升序数组

package test;

import java.util.Arrays;

public class LArray {

	public static void main(String[] args){
		int[] a={2,6,7,8}; int[] b={4,6,66,77,88,99,444,666,777,999};

	}
	
	public  static int[] uninArray(int[] a,int[] b){
		int left=0,mid=0,third=0;
		int[] tmpArr=new int[a.length+b.length];
		while (left< a.length && mid< b.length) {

			// 从两个数组中取出最小的放入中间数组
			if (a[left] <= b[mid]) {
