Question
Using java on Eclipse

Transcribed Image Text:Make a class 'StringMethods'.
It contains a private instance String variable.
Add these instance methods to your StringMethods class:
Constructor that takes a String literal and assigns it to the private String variable. Include getters and setters.
Check if this string equals the exact string contents of another string returns boolean true/false.
reallyEquals(String string)
Check if this string matches another but ignores letter casing.
caselessEquals(String string)
Check if the string shares an interned reference with another string.
internedEquals(String string)
A method that prints out the string. printThis()
A method that returns a char of the largest value in the string. getTopChar()
A method that prints out the string arranged in alphabetical order. printAlpha()
*Must handle the mixture of Capital and Lowercase letters*
For Example "OnceUponATime" Should output "AceeimnnOopTU"
A method that returns an int array of the ASCII char values of the characters in the string. getAsciiArray()
Make a method that returns a substring. getSubstring(int startlndex, int endlndex)
Make a static Class level overloaded method that returns a substring. getSubstring(String inputString, int startlndex, int
endlndex)
