java一维和多维数组的输出

`public class A {

public static void main(String[] args) {

    int[] arrays1 = new int[]{1, 2, 3, 4};
	
    // 1.for循环
 
    for (int i = 0; i < arrays1.length; i++) {
        System.out.println(arrays1[i]);
    }
    // 2.foreach
    for(int i : arrays1){
        System.out.println(i);
    }
    // 3.Arrays工具类，参数为多维数组会输出地址
    System.out.println(Arrays.toString(arrays1));

    // 4.Arrays工具类，可用于多维数组
    int[][] arrays2 = new int[][]{{1, 2}, {3, 4}};
    System.out.println(Arrays.deepToString(arrays2));
}

}
