All Java Relational Operators (Explained With Examples)

Q: What is the result of a relational operation?

The result of a relational operation is always a boolean value (true or false) based on whether the specified condition is met.

Q: Can different data types be compared using relational operators?

Relational operators can be used to compare values of compatible data types. For example, you can compare integers, floating-point numbers, characters, and other types that can be logically compared.

Q: What is the difference between == and equals() for string comparison?

The == operator checks if two references point to the same object in memory. The equals() method compares the content of two string objects.

Q: Can multiple relational operators be combined in a single expression?

Yes, you can combine multiple relational operators using logical operators (&&, ||, !) to create complex conditions for decision-making.

Q: What is short-circuit evaluation with respect to relational operators?

Short-circuit evaluation is a behavior in Java where the evaluation of a logical expression stops as soon as the final result can be determined. For example, in an && operation, if the left operand is false, the right operand is not evaluated because the result will always be false.

Q: Can I compare objects using relational operators?

Yes, you can compare objects using relational operators, but the behavior depends on how the objects' class defines the equals() method and the compareTo() method (for objects that implement the Comparable interface).

Q: Are relational operators applicable to boolean values?

Technically, boolean values are already the result of a comparison, so using relational operators with boolean values is generally unnecessary. However, you can still use them, and they will produce the expected boolean results.
