    public static void main(String[] args)
    {
        String str = "Welcome.com";
        StringBuilder sb = new StringBuilder(str);
        System.out.println("sb = "+sb);

        //Returns 8
        int indexPosition = sb.lastIndexOf("com");
        System.out.println("lastIndexOf(\"com\") = " + indexPosition);

        indexPosition = sb.lastIndexOf("abc");
        System.out.println("lastIndexOf(\"abc\") = " + indexPosition);
    }
}

Output

sb = Welcome.com
lastIndexOf("com") = 8
lastIndexOf("abc") = -1
