Exception:

An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions.

Program Code:

//Math Exception

Double result=10/0;

System.debug('Result='+result);

//DML Exception

Student__c record=new Student__c();

insert record;

//Null Pointer Exception

String str;

System.debug(str.toLowerCase());

throw new NullPointerException();
