一维数组、二维数组的循环遍历

一维数组遍历：

复制代码
package array;

public class ArrayTest01 {

public static void main(String[] args) {

    // 静态初始化一维数组
    int[] array1 = {1,2,3,4,5};

    for (int i = 0;i < array1.length;i ++){
        System.out.println(array1[i]);
    }

    // 动态初始化一维数组
    int[] array2 = new int[5];
    for (int j = 0;j < array2.length;j ++){
        System.out.println(array2[j]);
    }

}

}

二维数组遍历：

复制代码
package array;

public class ArrayTest04 {

public static void main(String[] args) {


    String[][] array = {
            {"java","python","c++"},
            {"cat","dog","pig"},
            {"Math","English","History"}
    };

    // 遍历二维数组
    for (int i = 0; i < array.length; i++) {
        for (int j = 0;j < array[i].length;j++){
            System.out.print(array[i][j]+" ");
        }
        System.out.println();
    }
}

}
复制代码
执行结果是：

java python c++
cat dog pig
Math English History
