Exception in java

• Exception is an Even.

• Exceptions are used to detect and handle errors during program execution so the program can continue safely.

Example

package practice;

public class Home {
     static int a=10;
    static int b=0;

    public static void main(String[] args) {
        System.out.println(a/b);
    }
}

Output

• Variable a is store value
• Variable b is store value and then java tries to calculate.
• but, 10/0 division by zero is impossible because 10/0 is Infinity. So, Java throw an exception.

Why Exception are used?
Exceptions are used in Java to handle errors safely without stopping the entire program suddenly.

• Prevent program crashes
• Handle runtime errors safely
• Maintain normal program flow
• Show meaningful error messages

Two types of Exception

1. Checked Exception
2. Unchecked Exception
