• Java Software
• Textbook

• A grade point average of 3.0 or above and an admission score test of at least 60
• A grade point average below 3.0 and an admission score test of at least 80

If the student does not meet either of the qualification criteria, print "Reject".

You can place and indent the if following an else, but a program with many nested if…else combinations soon grows very long and “deep,” and with indentations, later statements in the nest would move farther and farther to the right on the page.  For easier-to-read code, Java programmers constantly place each else and it’s subsequent if on the same line.

Remember that you reference character values using single quotation marks.

Indentations in the if...else are not required, but is standard usage. You vertically align the keyword if the keyword else, and then indent the action statements that depend on the evaluation.

You can code an if without an else, but it is illegal to code an else without an if.

When you create a block, you do not have to place multiple statements within it. It is perfectly legal to block a single statement.

An if statement ends with a semicolon.

Making a decision involves choosing between two alternative courses of action based on some value within a program.

You can use the if statement to make a decision based on a boolean expression that evaluates as true or false. If the boolean expression enclosed in parentheses within an if statement is true, then the subsequent statement or block will execute.

Within an if or an else statement, you can code as many dependent statements as you need, including other if and else statements. Nested if statements are particularly useful when two conditions must be met before some action occurs.

When you have a piece of code in which something can go wrong, you place the code in a try block. A try block consists of the following elements:

• The keyword try
• An opening curly bracket
• Statements that might cause Exceptions
• A closing curly bracket

You must code at least one catch block immediately following a try block. Each catch block can "catch" one type of Exception. You create a catch block by typing the following elements:

• The keyword catch
• An opening parenthesis
• An Exception type
• A name for an instance of the Exception type
• A closing parenthesis
• An opening curly bracket
• Statements that take the action you want to use to deal with the error condition
• A closing curly bracket

Additionally, if a method throws an Exception that will be caught, you must use the keyword throws followed by an Exception type in the method header.

The command line = in.readLine(); should be used to read in values.

Now use the following to hold the screen before you read in each time:
String line = in.readLine();

Then get a double value. Remember to use new like this:
new Double(line).doubleValue();

Then use the following line to clear the input so you can read from the keyboard again. line = in.readLine();

Then read in the test score like you did the value.
