这是一系列的java关于数组的程序

public class ArrayCopy {
	public static void main(String[] args) {
		String s[] = {"A", "B", "c" ,"d"};
		String sBak[] = new String[6];
		System.arraycopy(s, 0, sBak, 0, s.length); 
		for(int i=0; i<sBak.length; i++) {
			System.out.print(sBak[i] + "  ");
		}
		
		System.out.println();
		int intArr[][] = {{1,2},{1,2,3},{3,4}};
		int intArrBak[][] = new int[3][];
		System.arraycopy(intArr,0,intArrBak,0,intArr.length);
		intArrBak[2][1] = 100;
		for(int i=0; i<intArr.length; i++)
			for(int j=0; j<intArr[i].length; j++) {
				System.out.println(intArr[i][j] + "  ");
			}
		
	}
