Java variables store data, while control statements determine the order in which the program executes instructions.
- Types of Java Variables
Local Variables: Declared inside a method, constructor, or block.
Instance Variables: Belong to an object and store its individual data.
Static Variables: Belong to a class and are shared among its instances.
Java also supports data types such as int, char, boolean, double, and reference types like String.
- Types of Control Statements
Decision-Making: if, if-else, switch
Loops: for, while, do-while
Jump Statements: break, continue, return
Example
int age = 20;
if (age >= 18) {
System.out.println("Eligible");
} else {
System.out.println("Not eligible");
}
💡 In short: Variables store information, and control statements help Java programs make decisions, repeat tasks, and manage execution flow.
