1... Write a Java method with a one-character parameter that returns the parameter shifted one letter to the right ('A' becomes 'B', 'B' becomes 'C', etc.) if it is a capital letter; otherwise it returns the original parameter value.

2... Write a Java method that has a single parameter for an array of doubles and returns another array of doubles with the same length and has each element divided by 2.0.

3... Write a Java method that will search the array d for the value in the variable t. Use d and t as parameters. If the value of t is not found, the method returns -1. If the value of t is found, the method returns the first value of the subscript, sub, such that d[sub] has the same value as t. Data types:

char [] d; int sub; char t;
