19.text--敏感词替换

敏感词替换

将一些固定的词语替换成
使用String replace(旧值，新值)替换
注意点：只有返回值才是替换后的结果

public static void main(String[] args) {
    String talk = "TMD";

    //定义一个敏感词库
    String[] arr = {"TMD","CNM","SB","MLGB"};

    //循环得到数组中的每一个敏感词，依次进行替换
    for (int i = 0; i < arr.length; i++) {
        talk = talk.replace(arr[i], "***");
    }

    //替换TMD为***
    System.out.println(talk);
}
