Program Plan Intro

Finally block:

Finally block contains block of code and the block is executed after a try-catch block.

• If there is no errors in try block, finally statement is executed after try block executed.
• If there is error in try block, then catch block caught the exception, rest of try block is skipped, and then executes the finally statement.
• If there is error in try block, then catch block does not caught that exception, rest of try block is skipped, executes only finally statement, and then skip the rest of the code.
• Thus, finally block handle such case and it contains block of statement. Once try-catch block gets executed, finally block is executed.

General form for finally block:

// class definition

class class_name

{

//...

// Try block

try

{

// Try block statement

}

// Catch block

catch(Excep1 exObj)

{

// Catch block statement

}

// Catch block

catch(Excep2 exObj)

{

// Catch block statement

}

//...

//Finally block

finally

{

//finally block statement

}

//...

}

Given code:

//Try block

try

{

statement1;

statement2;

statement3;

}

//Catch block

catch (Exception1 ex1)

{

}

//Finally block

finally

{

statement4;

}

statement5;
