Program 34 : WAP to create a program to understand the concept of Exception Handling



import java.util.*;

class P34 {
public static void main(String[] args) {
int x,y,z;
                
Scanner sc = new Scanner(System.in);
                
try {
System.out.println("----------------------------");
System.out.print("Enter the first Number : ");
x = sc.nextInt();
                
System.out.print("Enter the Second Number : ");
y = sc.nextInt();
System.out.println("----------------------------");
                
z = x/y;
                
System.out.println("the Division is : " + z);
System.out.println("----------------------------");
} 
                
catch(ArithmeticException ex1) {
System.out.println("Are you trying to / by zero?");
System.out.println("the error is : " + ex1);
System.out.println("----------------------------");
                
                
}
catch(InputMismatchException ex2) {
System.out.println("Enter Numbers only.");
System.out.println("the error is : " + ex2);
System.out.println("----------------------------");
}
                
finally {
System.out.println("This is finally Block");
System.out.println("----------------------------");
}
}
}

Copy Code

Expected Output: Scenario 1: Division by Zero
----------------------------
Enter the first Number : 10
Enter the Second Number : 0
----------------------------
Are you trying to / by zero?
the error is : java.lang.ArithmeticException: / by zero
----------------------------
This is finally Block
----------------------------
Expected Output: Scenario 2: Invalid Input (Non-Integer)
----------------------------
Enter the first Number : 10
Enter the Second Number : abc
----------------------------
Enter Numbers only.
the error is : java.util.InputMismatchException
----------------------------
This is finally Block
----------------------------

Program 35 : WAP to create a program to understand the concept of Exception Handling and Input through BufferedReader


import java.io.*;

 class P35 {
public static void main(String[] args) throws IOException {
                
int empid;
String empname;
double salary;
                
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
                
System.out.println("----------------------------");
System.out.print("Enter Employee ID : ");
empid = Integer.parseInt(br.readLine());
                
System.out.print("Enter Employee Name : ");
empname = br.readLine();
                
System.out.print("Enter Employee Salary : ");
salary = Double.parseDouble(br.readLine());
System.out.println("----------------------------");
                
System.out.println("Employee Name : " + empname);
System.out.println("Employee ID : " + empid);
System.out.println("Employee Salary : " + salary);
System.out.println("----------------------------");
                
}
}

Copy Code

Expected Output:
----------------------------
Enter Employee ID : 101
Enter Employee Name : Hardik Srivastava
Enter Employee Salary : 50000.75
----------------------------
Employee Name : John Doe
Employee ID : 101
Employee Salary : 50000.75
----------------------------
