Variables

Below is a Java program demonstrating assignment statements and various operators, adapted from the structure of your previous Python example. It includes basic data types, assignment statements, and expressions using different operators.

public class AssignmentAndOperators { public static void main(String[] args) { // Assignment statements int age = 25; // Simple assignment (integer) double height = 5.9; // Simple assignment (double) boolean isStudent = true; // Simple assignment (boolean) String name = "Alice"; // Simple assignment (String) char initial = 'A'; // Simple assignment (character)

    // Compound assignment and arithmetic operators

    age += 1; // age = age + 1 (now 26)

    double heightInMeters = height * 0.3048; // Convert feet to meters

    // Relational and logical operators

    boolean isAdult = age >= 18; // Relational operator

    boolean canEnroll = isStudent && isAdult; // Logical operator

    // String concatenation operator

    String greeting = "Hello, " + name;

    // Increment operator

    int yearsUntilRetirement = 65 - age++; // Post-increment: uses age (26), then increments to 27

    // Ternary operator

    String status = age >= 18 ? "Adult" : "Minor";

    // Output results

    System.out.printf("Age: %d%n", age);

    System.out.printf("Height: %.1f feet (%.2f meters)%n", height, heightInMeters);

    System.out.printf("Is student? %b%n", isStudent);

    System.out.printf("Name: %s%n", name);

    System.out.printf("Initial: %c%n", initial);

    System.out.printf("Years until retirement: %d%n", yearsUntilRetirement);

    System.out.printf("Can enroll? %b%n", canEnroll);

    System.out.printf("Greeting: %s%n", greeting);

    System.out.printf("Status: %s%n", status);

}
