1Z0-811 Java Basics and Syntax Practice Question
Which statement about try-catch is true?
⚠ Common exam trap
Oracle often tests the misconception that a catch block can handle multiple unrelated exception types without using multi-catch syntax, leading candidates to incorrectly select option D as false, when in fact a single catch block can only handle one exception type (or a union via multi-catch, but that is still a single catch block with a disjunctive type).

Correct answer & explanation
✓
A catch block can only handle one type of exception.
In Java, a catch block is defined with a single exception type parameter, meaning it can only handle one specific type of exception (or its subclasses if the parameter is a superclass). This is enforced by the language syntax: `catch (ExceptionType e)` allows only one exception type per catch clause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A finally block is always required.
Why it's wrong here
Not required; catch alone is sufficient.
- ✗
A try block without a catch or finally is legal.
Why it's wrong here
Illegal; must have at least one catch or finally.
- ✗
A try block can have multiple catch blocks for the same exception type.
Why it's wrong here
Not allowed; duplicate catch types cause error.
- ✓
A catch block can only handle one type of exception.
Why this is correct
Correct: each catch block handles one exception type (unless multi-catch).
