Question

Q2.1 Write a Java program called Div that takes 2 (two) double command-line arguments as inputs, dividend and divisor (in that order) and performs a division operation. Your program either prints the quotient or an error if the divisor is zero. The divisor is the number you divide the dividend by.

public class Div

{

public static void main ( String[] args )

{

// WRITE YOUR CODE HERE

}

}

Q2.2

Write a Java program called IntCheck that examines the integer variable x, printing GT (greater than) if x is greater than 100, LT (less than) if x is less than 100 and EQ (equal) if x is 100.

public class IntCheck { public static void main ( String[] args ) { int x = Integer.parseInt(args[0]); // WRITE YOUR CODE HERE } }

Answer 1

Code for Q2.1 in java , given below :-

public class Div
{
   public static void main(String[] args) {
        double   ans;
       double dividend=1;
       double divisor=1;
      
        for(int i=0;i<args.length;i++)
        {
          dividend = Double.parseDouble(args[0]); // get command line argument dividend as a string and convert to double
          divisor = Double.parseDouble(args[1]);   //get command line argument divisor as a stringand convert to double
          System.out.println(args[i]);   //print dividend and divisor
        }
         
           if(divisor==0)
           {
               System.out.println("error, divisor is Zero!!!;"); //if divisor is zero
           }
           else if(divisor!=0)
           {
               ans=dividend/divisor;
               System.out.println(ans); //print answer
           }
   }
}

Code for Q2.2 in java , given below :-

public class IntCheck
{
   public static void main(String[] args) {
        int x=0;
       x = Integer.parseInt(args[0]); // get number as command line argument as a string and convert it into integer
      
     
           if(x==100)
           {
               System.out.println("EQ (equal)"); // if x if equal to 100
           }
           else if(x>100)
           {
             
               System.out.println("GT (greater than) "); // if x is greater than 100
           }
           else if(x<100)
           {
             
               System.out.println("LT (less than) "); // if x is less than 100
           }
   }
}
