用java把二个数组合并成一个数组 并按升序排列;

class lx4{
//把二个数组合并成一个数组 并按升序排列;
public static void main(String[] args){

	int[] arr = {5,23,35,17,78,36,7,45,12};
	int[] arr1 = {6,24,38,74,47,10};
	int[] arr2 = MergeNewArr(arr,arr1);
	printArr(arr2);
	SortArr(arr2);
	//换行		
	System.out.println();
	//重新打印
	printArr(arr2);
	}
//二个数组合并成一个数组;Merge:合并;New:新的;
public static int[] MergeNewArr(int[] arr,int[] arr1){
	
	int[] arr2 = new int[arr.length + arr1.length];
	for(int i=0;i
