Java Variables:
- There are five types of variables in java they are:
- String: it stores name in double quotes
- Int: stores integral numbers and non-decimal numbers.
- float: stores decimal floating digits.
- Char: stores single characters in single quotes.
- Boolean: Evaluates a given condition.
String:
public class Main { public static void main(String[] args) { String name = "Prequelcoding"; System.out.println(name); } } Int: public class Main { public static void main(String[] args) { int myNum = 4; System.out.println(myNum); } } Adding two integers: public class Main { public static void main(String[] args) { int myNum = 4; int myNum2 = 10; System.out.println(myNum + myNum2); } } Multiplying Two Integers: public class Main { public static void main(String[] args) { int myNum = 4; int myNum2 = 10; System.out.println(myNum * myNum2); } } Subtracting Two Integers: public class Main { public static void main(String[] args) { int myNum = 4; int myNum2 = 10; System.out.println(myNum2 - myNum); } } Dividing Two Integers: public class Main { public static void main(String[] args) { int myNum = 9; int myNum2 = 72; System.out.println(myNum2 /myNum); } } Char implementation: public class Main { public static void main(String[] args) { char name = 'P'; System.out.println(name); } }
