Arrays.asList(数组).contains("字符串");

String[] ss = {"1","2","3"};
String s = "2";
boolean isContains = Arrays.asList(ss).contains(s);

Answer 5

public boolean contains(String[] arrays,String key){
boolean result=false;
for (String string : arrays) {
if(string.contains(key)){
result=true;
break;
}
}
return result;
}
