数组演练——复制数组

public class OneArray_07 {public static void main(String[] args) {copy();}public static void copy() { // 数组复制int copy1[] = new int[] { 23, 12, 67, 89, 56, 47, 13 }; // 声明数组并初始化// 声明数组长度与copy1数组的长度相同的数组，也就是备份数组int copy2[] = new int[copy1.length]; System.out.println("数组copy1中的元素如下：");for (int i = 0; i < copy1.length; i++) {// 循环显示copy1数组元素System.out.print(copy1[i] + "  ");if ((i + 1) % 4 == 0)System.out.println();}System.arraycopy(copy1, 0, copy2, 0, copy1.length); // 将数组copy1复制给数组copy2System.out.println("\n复制的新数组copy2中的元素如下：");for (int i = 0; i < copy2.length; i++) {// 循环显示copy2数组元素System.out.print(copy2[i] + "  ");if ((i + 1) % 4 == 0)System.out.println();}}}
