Word in a word java

SO my problem is that i have a string and i need to search in that string if it is another string. Basically i just want to search if lets say "ala" exists in "balama". I thought about Search by letter by letter but its consuming and if exists more than 2 or 3 words i can't do it. Any suggestions or there is a method in the string? I saw the CompareTO method but doesn't seem to work on partial words in a string. Just the idea to get me started. Thank you for you'r time and consideration.

Solution

  • The String method you are looking for is called indexOf:

    String testStr = "Vlad Adrian";

        String substr = "ad";

        int pstn = testStr.indexOf(substr);

        System.out.println(substr + " position in " + testStr + " is " + pstn);

    Prints

    ad position in Vlad Adrian is 2

    If the substring is not found, the method returns -1
