第一種方法：遍歷數(shù)組
String[] arr1 = {"1","2","3","4","6","7"};
for (int i = 0; i < arr1.length; i++) {if("5".equals(arr1[i])) {System.out.PRintln("包含");}else {System.out.println("不包含");}}
第二種方法：先把數(shù)組轉(zhuǎn)換成list；再判斷contains
String[] arr = {"1","2","3","4","6","7"};List<String> list=Arrays.asList(arr);System.out.println(list.contains("5"));
