DAA 3 A - COMPUTE A/B

3 A - Write a Java program to read two integers a and b. Compute a/b and print, when b is not zero. Raise an exception when b is equal to zero.

import java.util.Scanner;
public class lab3a 
{
lab3a()
{
int a,b;
float c;
Scanner sc=new Scanner(System.in);
try
{
System.out.println("Enter the value of a");
a=sc.nextInt();
System.out.println("Enter the value of b");
b=sc.nextInt();
sc.close();
if(b==0)
throw new ArithmeticException(" Divide by Zero Error");
c=(float)a/b;
System.out.println("value of a is: "+a);
System.out.println("value of b is: "+b);
System.out.println("a/b is: "+c);
}
catch(ArithmeticException e)
{
System.out.println("ERROR..!!");
e.printStackTrace();
}
}
public static void main(String srgs[])
{
new lab3a();
}
