两个有序数组合并为一个有序数组

把两个有序数组合并为一个有序数组，例如：

数组A：1,2,2,3,5,6,7,7

数组B：1,2,4,5,8,8,9,10,11,12,12,13,14

合并后应该为：

1, 1, 2, 2, 2, 3, 4, 5, 5, 6, 7, 7, 8, 8, 9, 10, 11, 12, 12, 13, 14

以下是示例代码：

public void mergeArrays(){
int[] a = {1,2,2,3,5,6,7,7};
int[] b = {1,2,4,5,8,8,9,10,11,12,12,13,14};
int[] result = new int[a.length + b.length];
int i=0, j=0, k=0;
while (i<a.length && j<b.length){
if(a[i] <= b[j]){
result[k++] = a[i++];
}else{
result[k++] = b[j++];
}
}
while (i < a.length){
result[k++] = a[i++];
}
while (j < b.length){
result[k++] = b[j++];
}
System.out.println(Arrays.toString(result));
}

输出为：

[1, 1, 2, 2, 2, 3, 4, 5, 5, 6, 7, 7, 8, 8, 9, 10, 11, 12, 12, 13, 14]
