This is a Java program that demonstrates the use of primitive data types and strings. The program declares several variables of different primitive data types, including an integer (age), a double-precision floating-point number (wei), a character (gen), and two boolean values (isMarried and isQualified).
The program also declares a string variable called name and initializes it with the value "Ram Kumar". The program then uses System.out.println() statements to print out the values of the variables. For example, the program prints out whether isMarried and isQualified are true or false, and it prints out name, age, gen, and wei along with descriptive strings.
public class Primitive_Datatype { public static void main(String[] args) { String res = null; String name = "Ram Kumar"; int age = 29; double wei = 77.15; char gen = 'M'; boolean isMarried = true; boolean isQualified = false; System.out.println( "isMarried : " + isMarried); System.out.println("isQualified : " + isQualified); System.out.println( name + " is " + age + " years old "); System.out.println( "His gender is : " + gen); System.out.println( name + " weight is " + wei + " kg."); } }
isMarried : true isQualified : false Ram Kumar is 29 years old His gender is : M Ram Kumar weight is 77.15 kg.
