7.WAP to print details about you i.e., your name and age using VARIABLE IN JAVA only.

Answer 1

With Scanner Class your answer will be:
import java.util.*;
class program
{
void main ()
{
Scanner ob = new Scanner (System.in);
String n, a;
System.out.println("Enter your name");
n = ob.nextLine();
System.out.println("Enter your age");
a = ob.nextLine();
System.out.println("Your name is " + n);
System.out.println("Your age is " + a);
}
}

Without Scanner Class your answer will be:
class program
{
void main (String a, String n)
{
System.out.println("Your name is " + n);
System.out.println("Your age is " + a);
}
}
