StringContainsString.java

package com.codeFactory;
import org.apache.commons.lang3.StringUtils;
/**

public class StringContainsString {
public static void main(String... args) {
  String str = "Love is a friendship set to music";
System.out.println("String to search: " + str);
System.out.println("\nUsing String.contains():");
  System.out.println("str.contains(\"love\"): " + str.contains("love"));
  System.out.println("str.contains(\"Love\"): " + str.contains("Love"));
System.out.println("\nUsing String.indexOf() processing:");
  System.out.println("(str.indexOf(\"love\") > -1 ? true : false): " + (str.indexOf("love") > -1 ? true : false));
  System.out.println("(str.indexOf(\"Love\") > -1 ? true : false): " + (str.indexOf("Love") > -1 ? true : false));
System.out.println("\nUsing StringUtils.contains():");
  System.out.println("StringUtils.contains(str, \"love\"): " + StringUtils.contains(str, "love"));
  System.out.println("StringUtils.contains(str, \"Love\"): " + StringUtils.contains(str, "Love"));
 }
}

Output :

String to search: Love is a friendship set to music
Using String.contains():
str.contains("love"): false
str.contains("Love"): true
Using String.indexOf() processing:
(str.indexOf("love") > -1 ? true : false): false
(str.indexOf("Love") > -1 ? true : false): true
Using StringUtils.contains():
StringUtils.contains(str, "love"): false
StringUtils.contains(str, "Love"): true

Note : i used commons-lang3-3.1.jar for StringUtils.
