About relational operators
Relational operators are used to compare two values or to check the equality and return a Boolean value such as true or false. The following are the relational operators in Java:
Less than (<): Returns true if the first operand is less than the second operand.
Less than or equal to (<=): Returns true if the first operand is less than or equal to the second operand.
Greater than (>): Returns true if the first operand is greater than the second operand.
Greater than or equal to (>=): Returns true if the first operand is greater than or equal to the second operand.
Equal to (==): Returns true if the two operands are equal.
Not equal to (!=): Returns true if the two operands are not equal.
Here are some examples of how relational operators are used in Java:
Java - Relational operator
int x = 10;
int y = 20;
// Check if x is less than y
boolean lessThan = x < y; // true
// Check if x is less than or equal to y
boolean lessThanOrEqualTo = x <= y; // true
// Check if x is greater than y
boolean greaterThan = x > y; // false
// Check if x is greater than or equal to y
boolean greaterThanOrEqualTo = x >= y; // false
// Check if x is equal to y
boolean equalTo = x == y; // false
// Check if x is not equal to y
boolean notEqualTo = x != y; // true
The operands of a relational operator can be of any type, as long as they are comparable. The result of a relational operation is a Boolean value.
Here are some other important points to keep in mind about relational operators in Java:
Relational operators are evaluated from left to right.
The operands of a relational operator must be of comparable types.
The result of a relational operation is a Boolean value.
Relational operators can be used to make decisions in your code, such as:
If the user is over 18, allow them to enter the website.
If the number is even, print "The number is even".
If the two strings are equal, print "The strings are equal".
Relational operators can be a powerful tool for making decisions in your code, but they can also be difficult to understand. It is important to carefully understand the behavior of relational operators before using them in your code.
