boolean b = Arrays.asList(stringArray).contains("a");System.out.println(b);// true 1. 2. 先使用Arrays.asList()将Array转换成List,这样就可以用动态链表的contains函数来判断元素是否包含在链表中。 4、连接两个数组 int[] intArray = { 1, 2, 3, 4, 5 };int[] intArray2 = { 6, 7, ...
System.out.println(s1.replaceAll("monke", "likessy"));//这个方法是指替换字符串中的指定内容,把字符串里的monke部分替换成likessy,所以原来字符串是monkey10y24现在是likessyy10y24 String s5="a,b,c,r,t,s,x,c"; String[] array1=s5.split(",");//根据我们表达的意识把他们变为数组 for(int...
