1. To understand data input using a Java Scanner
2. To practice Java data types and casting
3. To learn the Java string methods

1. Use Scanner to read in an integer x and display it.
2. Use Scanner to read a floating-point value d.
3. Type cast d to an int value and store the result in y.
4. Display d and y clearly labeled. d should be formatted to two decimal places.
5. Type cast d to a byte value and store the result in b.

• Add a new String variable and set it to be equal to your full name.
• Call the following methods on that string, each in a separate print line:
  1. length()
  2. indexOf() the first letter of your last name
  3. charAt() the first letter and the last
  4. substring() the third through the seventh characters
  5. toUpperCase() the string
  6. toLowerCase() the string
