In Java Please

The class you write is called Pseudo and it mimics some of the attributes of the String class. After you write the methods in the Pseudo class, you can test them by comparing the return values from methods in your class to the return values from the String class.

Part A - Defining String Functions NOTE:To implement the methods below, you cannot use the String methods indexof, toUpperCase, substring, or equals. All of the methods below must use the contents of the character array stored in the Pseudo class! Declare a public static method called charAt that takes a char array parameter, and an index parameter and returns the character from the array at the index specified. You can assume that the index is valid, i.e. between 0 and String,length()- 1. 1. Declare a public static method called indexOf that takes a char array parameter, character parameter and returns the index in the character array of the first occurrence of that character or -1 if the character is not found. 2. Declare a public static method called toUpperCase takes a char array parameter and returns a String with the contents of the character array converted to upper case. Do not change the contents of the character array! 3
