What are the different types of relational operators available in Java and how do they work?
Java provides six relational operators: `==` (equal to), `!=` (not equal to), `>` (greater than), `<` (less than), `>=` (greater than or equal to), and `<=` (less than or equal to). These operators compare two values or expressions and return a boolean value (`true` or `false`) based on the comparison outcome.
How do relational operators in Java differ from logical operators?
Relational operators in Java compare two values to determine their relationship, such as equality or inequality (e.g., ==, !=, <, >), while logical operators combine multiple boolean expressions to evaluate overall logic (e.g., &&, ||, !). Relational operators result in a boolean value, whereas logical operators operate on boolean values.
How do relational operators handle object comparisons in Java?
Relational operators in Java, such as '==', compare object references rather than their content, meaning they check if two reference variables point to the same object in memory. To compare the content of objects, methods like 'equals()' should be used.
Can relational operators in Java be used with all data types?
No, relational operators in Java can only be used with primitive data types like `int`, `float`, `double`, `long`, `char`, `short`, and `byte`. They cannot be used directly with objects or non-primitive types such as `String` or user-defined classes.
What is the precedence of relational operators in Java compared to other operators?
In Java, relational operators have a lower precedence than arithmetic operators but higher precedence than logical operators such as `&&` and `||`. Specifically, relational operators like `<`, `<=`, `>`, and `>=` fall below arithmetic operators like `+`, `-`, `*`, `/` in precedence and above logical operators.
