Real-Life Examples
Often in our examples, we simplify variable names to match their data type (myInt or myNum for int types, myChar for char types, and so on). This is done to avoid confusion.
However, for a practical example of using variables, we have created a program that stores different data about a college student:
Example
// Student data
String studentName = "John Doe";
int studentID = 15;
int studentAge = 23;
float studentFee = 75.25f;
char studentGrade = 'B';
// Print variables
System.out.println("Student name: " + studentName);
System.out.println("Student id: " + studentID);
System.out.println("Student age: " + studentAge);
System.out.println("Student fee: " + studentFee);
System.out.println("Student grade: " + studentGrade);
