Question

1. Fill in the code for the following class methods.

1. The following method returns the position of the firstoccurrence of a given character in a given string. The positionstarts from 0 for the first character in the string. The methodshould return -1 if the character does not appear in the string.For example, the call indexOf('t',"iteration") would return 1, andthe call indexOf('s',"iteration") would return -1. (You are notallowed to use the String indexOf method.)

    public static int indexOf(char c, String str)
           {
           // fill this in
           }

2. Given two String parameters, the following method returns trueif they are the same string of characters, and false otherwise.Note: You cannot use the equals String method; in otherwords, you actually have to write the code that compares the twostrings character by character.

    public static boolean stringsAreEqual(String s1, String s2)
           {
           // fill this in
           }

Explanation / Answer

Dear... Here is the code... 1)    public staticint indexOf(char c,String str)    {
          inti;          for(i=0;i<str.length();i++          {            if(str.charAt(i)==c)                return i;          }           return-1;     } 2)    public staticboolean stringsAreEqual(String s1, String s2)     {        if(s1.equals(s2))             return true;         else           return false;      } Hope thiswill help you... Hope thiswill help you...
