Java Concepts
1.public class MyClass {
// Code goes here
}
2.public static void main(String[] args) {
System.out.println("Hello, World!");
}
3.Primitive types: int, float, double, char, boolean
Reference types (objects): String, Arrays, custom classes
int age = 25;
String name = "Alice";
boolean isJavaFun = true;
4.if (age >= 18) {
System.out.println("Adult");
} else {
System.out.println("Minor");
}
int day = 2;
switch(day) {
case 1: System.out.println("Monday"); break;
