HWJ5 - More string exercises:

Start with the file below and use it to create the 5 methods described. (note example of indexof below).

For index of look at the example below:

Create guessing game from bottom of if-then page make it repeat, so it will keep asking until they guess the number.

EXAMPLE OF INDEXOF BELOW

public void testIndexOf()
    {
        String phrase="Deering HS";
        System.out.println(phrase.indexOf("e"));  //it would spit out 1
        System.out.println(phrase.indexOf("ring"));  //it would spit out 3
        System.out.println(phrase.indexOf("z"));  //it would spit out -1 b/c it is not in the word

		//if we wanted to see if the char scannedChar is in HIDDENWORD we could write
        if (HIDDENWORD.indexOf(scannedChar)==-1)
        	// IT IS NOT IN THE WORD
        else 
        	//it is in the word
        
        // for the gender and age we might say
        if (gender.equals("female")&& age>=20 && age<=39)
