Java judgment string contains a character segment

1. Using the IndexOf () method

String str = "1234567";

if (Str.indexof ("23")! =-1) {
System.out.println ("contains this string");

}

public void Test1 () {

String string = "Good morning Everyone";
String sub = "Morning";
int a = String.IndexOf (sub);

if (a >= 0) {
System.out.println ("Morning position in the string:" + a);
String SS1 = string.substring (0, A + sub.length ());
String SS2 = string.substring (A + sub.length (), String.Length ());
SYSTEM.OUT.PRINTLN ("The result you need is:" + SS1);
System.out.println ("Deleted characters are:" + SS2);
} else {
System.out.println ("does not exist");
}
}

2. Using the Repalce () method

public class Test {public  static void Main (string[] args) {   String S1 = "abc";   String s2 = "1111abcdefe";    if (S2.contains (S1)) {    System.out.println ("S2 contains S1");    Remove S1    s2 = s2.replace (s2.substring (S2.indexof (S1), S2.length ()), "");    SYSTEM.OUT.PRINTLN (s2);   } else{    System.out.println ("S2 does not contain S1");}}}
