a. Sections 2.9, 2.10, 2.11, 2.16
2. Overview
Demonstrate using char and String types and some of the operations associated
with them. Also, use Scanner and Input Dialog to input data. To properly input
data you will need to convert the input to the correct data type to support that
data.
3. Tasks
a. Scanner input – write a program named InputScanner.java that
demonstrates each of the following Scanner inputs:
i. nextByte() reads an integer of the byte type
ii. nextShort() reads an integer of the short type
iii. nextInt() reads an integer of the int type
iv. nextLong() reads an integer of the long type
v. nextFloat() reads an number of the float type
vi. nextDouble() reads an number of the double type
vii. next() reads a string that ends before a whitespace
viii. nextLine() reads a line of characters (a string ending with a line
separator)
You should demonstrate it works by displaying to the monitor the values
that were input.
b. Input Dialogs – repeat 3.a but use input dialogs instead of Scanner and
name the program InputDialog.java.
