public class JavaExceptionExample{
public static void main(String args[]){
try{
//code that may raise exception
int data=100/0;
}catch(ArithmeticException e){System.out.println(e);}
//rest code of the program
System.out.println("rest of the code...");
}
}
I use try & catch blocks to handle any exceptions in my code.
I am familiar with major checked and unchecked exceptions and
handle it accordingly to make my code execution smooth
