Name three blocks for exception handling in Java.

In Java, three main blocks are used for exception handling:

• try — a block where code that might throw exceptions is placed.
• catch — a block that catches and handles exceptions thrown in try.
• finally — a block that always executes after try and catch, regardless of whether an exception occurred or not, usually used for resource cleanup.

Example:

try {
    // code that might throw an exception
} catch (ExceptionType e) {
    // handle the exception
} finally {
    // code that will run in any case
}
