Java programming

4.1 Describe what is meant by "method overloading."

Method overloading requires that the methods have different signatures. What parts of a method are used in the signature?

4.2 Write a boolean method named isSymmetric that accepts a String as its single parameter and returns true if the String has the same first and last characters, and false otherwise.

If the passed String is empty or has only one character, return true. You don't have to declare the class; just write the specified method.

4.3 Suppose GPSStudent is a Java class with the following instance variables: name (a String), USTID (a long), and program (a String).

Write a constructor for the GPSStudent class that takes three parameters as initial values of the variables and initializes each instance variable with its corresponding parameter. Use this reference in the constructor.
