How to go from catch block to try block in java?
I have some logic inside the try block. If exception arises, then I am catching the exception in the catch block.
Example
try
// line 1
catch(SocketException se)
// again goto try block
If control comes inside catch block then again I want to execute line 1 in try block but how to go again try block? Can we use Label?

If you want to loop back to an earlier point in your code, put your code in a loop.

You can put the code in a method and call that method from the catch resulting to execute a try again.

Depending on your situation, recursion or a nested try are also valid options, although generally much less desirable.

If you want to loop back to an earlier point in your code, put your code in a loop.
while (true)
try
// line 1 (something that might throw an exception)
break;
catch (SocketException se)
// handle the error
If the code in your try block executes successfully, the break will be encountered, and your loop will exit. If a SocketException is thrown, execution will return the the top of the while loop and your line 1 will be repeated.
If you only want to retry a fixed number of times (to avoid being stuck indefinitely), then you could use a for loop instead of a while loop.
