java---数组的学习

几个关于java数组操作的学习

//输出一个数组

import java.lang.reflect.Array;import java.util.Arrays;public class array {public static void main(String[] args) {int[] intArray = { 1, 2, 3, 4, 5 };String intArrayString = Arrays.toString(intArray);System.out.println(intArray);System.out.println(intArrayString);}}

//检查一个数组是否包含某个值 

import java.lang.reflect.Array;import java.util.Arrays;public class array {public static void main(String[] args) {String[] stringArray = {"a","b","c","d","e"};boolean b = Arrays.asList(stringArray).contains("f");System.out.println(b);}}

若

boolean b = Arrays.asList(stringArray).contains("f");

结果为false.

若

boolean b = Arrays.asList(stringArray).contains("a");

结果为true.
