java基础：数组的使用

For-Each循环

 public static void main(String[] args) {
        int[]arrays={1,2,3,4,5};
        //使用增强for循环遍历数组
        for (int array : arrays) {
            System.out.println(array);
        }
    }

数组作返回值

 public static void main(String[] args) {
        int[]arrays={1,2,3,4,5};
        arrays[0]=max(arrays);
        System.out.println(arrays[0]);
    }
    public static int max(int[]arrays){
        int max=arrays[0];
        for (int i = 0; i <=arrays.length-1 ; i++) {
            if (max<arrays[i]){
                max=arrays[i];
            }
        }
        return max;
    }

数组作方法入参 

public class ArrayDemo06 {
    public static void main(String[] args) {
        int[] arrays = {1,2,3,4,5};

        /*for (int array: arrays){
            System.out.println(array);
        }

         */
        printArray(arrays);

    }
    //打印数组变量
    public static void printArray(int[] arrays) {
        for (int i = 0; i < arrays.length; i++) {
            System.out.println(arrays[i]);
        }
    }
