When we want to compare value of two variables for various means, relational operators are used. After comparing these values we may take several decision in the program.

Relational operators can be called as comparison operators. For example, we want to find the largest of two integers, we can use '>' operators to perform comparison.

The expressions such as,

val > 12 or cal < sal

contains the relational operator. So, they can be termed as relational expression. The value of value relational expression can be either true or false.

For example, if cal = 10 and sal = 15 then,

cal < sal is true

while

sal > 20 is false

Java supports six different relational operators. These are listed and explained in the table below.

Observe the following relational expressions which returns boolean values

36 > 42 true

52.14 < 45 false

10 < 8 + 9 false

-74 ! = 0 false

When the arithmetic expressions are used on either side of a relational operator, the arithmetic expression will be evaluated first and then the results are compared. In short, the arithmetic operators are having highest priority over relational operators.
