No, in Java, you cannot execute two catch blocks together. When an exception is thrown in a try block, Java will execute only the catch block that matches the exception type and then proceed with the subsequent code. It won't execute multiple catch blocks simultaneously.

[funshhcreator]

Hi, two catch blocks can be used in single try block. But only one of the catch block will handle your exception so only one catch block will be executed.

[VivekYadav-sgte]

Yes we can use multiple catch block but the because if the Exception in child class we would write first and after that we write parent Exception.

For eg:-
try{
System.out.println(10/0)
}
Catch(Arithmetic Exception e)
{
e.printStackTrace();
}
Catch(Exception e)
{
e.printStackTrace();
}

[babu]

Yes based on rxception hirerachy from most specific to most general. At a time only one exception occurs snd one catch block will be executed even thogh we have multiple catch blocks.

[naveenkumarm]

We can do only one catch block to execute

[jyothsnakonakonda]

Yes, It is possible but based on the exception hierarchy.

[jaiyanthbalasubramaniam]

No, it's not possible for two catch blocks to execute simultaneously in a single try-catch block. In exception handling, once an exception is caught by a catch block, the program control exits the try-catch block, and subsequent catch blocks are not executed. Each catch block is designed to handle a specific type of exception, and only the appropriate catch block will execute based on the type of exception thrown.

[richanema]

No if any catch block gets executed it simply means compilar has found the exception then he will never go to the next one.Compilar will only execute the catch block which comes first and is appropriate.

[gourinesare]

Yes we can execute multiple catch block with single try block

[Maheshdy]

It is posdible to execute two catch block together but these two catch block contains the two different exceptions if they contains tge same then first catch block will execute only

[mahisentertainment]

No, we can execute one catch block only at a time

[smitamokashe]

No. Multiple catch blocks will not execute together. if any catch block gets executed it means compilar has found the exception then it will never go to the next catch block.
Compilar will only execute the catch block which comes first.

[sowmyarama]

No, only one catch block will execute at a time. 2 catches together is not possible.

[sonalidhavre]

No, you cannot execute two catch blocks together in most programming languages. Catch blocks are typically designed to handle specific types of exceptions, and only one catch block will be executed for a given exception.

[mokshakrishnamurthy]

No, For an exception only one catch block can be executed at a time.

[adepunaresh]

Yes, inner catch blocks, try and catch block inside catch block is simulator of two catch blocks executing together. 😂

[sjbhaskar]

Is possible but based on the exception hierarchy

[Itsme_Saku]

No it will not possible . Because either only try block will execute or 1 catch block will execute

[ruchavaidya]

No. It is not possible to execute 2 catch blocks together.

[CrazyGitu]

No, we may have multiple catch blocks but only 1 catch can be executed.
