Java Program

Given the declaration String s = letterhead; and using the String class

1. Write the expression to find index of the character h.

2. Write the expression to retrieve the character r from the String.

3. Write the expression to get the substring ette.

4. Write the expression to find the index location of the last 'e'.

Using the Math class

1. Write the expression to calculate e^1.7

2. Write the expression to find the larger of two values x and y

3. Write the expression to generate a random number in the range [0.0, 1.0)

4. Write the expression to generate a random number in the range [0.0, 20.0) (hint: this wont be a new method, but will require some math after you make the call).

5. Write the expression to generate a random number in the range [5.0, 6.0) (same hint as before)

6. Write the expression to generate a random number in the range [10.0, 15.0) (think about combining the 2 steps from 4 and 5)

7. Write the expression to generate a random integer in the range [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

More searching through the API

1. Write a statement to instantiate a Point object with coordinates (3, 4) and binding it to an appropriate reference variable.

2. What package do you need to import to use a Point object?

3. What are the coordinates of a Point object if you don't specify any?
