As you are going to learn, the concept of type is a very important part of many programming languages. Variables are also an important part, and must be declared with a specific type in Java. A variable can be thought of as a box, and the type of a variable can be thought of a label on the box — making sure that it can only hold contents of that particular type.
In Java, there are eight primitive types to choose from — byte, char, short, int, long, float, double, and boolean . int , for instance, can hold whole numbers like 42 , 1000 , or 5679 . Another type, double, can hold floating point numbers like 3.14, 2.72, or 1.414. The type String is a little different, and you will learn this later on in the course. All you need to know now, though, is that a variable of type String can be use to hold text in double quotes, such as “Hello, world!” or “CS18000”. Your job below, is to implement a program to prompt a student for some information, then display it in a business card format. Doing so will introduce you to the types int, double, and String.
Description:
Write a program that prompts a student, using Scanner, for their name (a String ) , age (an int ) , GPA (a double), major (a String), and email (a String).
The information should then be displayed in the business card format shown on the example output, which is located on the next page.
