Relational Operators in Dart Programming
Relational operators are used in cases where we want to compare two operands. The result when we use a relational operator between two operands is always a Boolean value.
There are different types of relational operators present in Dart. In the table shown below all the relational operators present in dart are mentioned.
Let's take a case where we have two variables x and y, with values 20 and 30 respectively.
Consider the table shown below as a reference −
| Operator | Description | Output |
|---|---|---|
| > | Greater than | x > y = false |
| < | Less than | x < y = true |
| >= | Greater than or equal to | x >= y = false |
| <= | Less than or equal to | x <= y = true |
| == | Equal to | x == y = false |
| != | Not equal to | x != y = true |
Let's make use of all these relational operators in dart.
Example
Consider the example shown below −
void main(){
var x = 20, y = 30;
print("x > y is: ${x > y}");
print("x < y is: ${x < y}");
print("x >= y is: ${x >= y}");
print("x <= y is: ${x <= y}");
print("x == y is: ${x == y}");
print("x != y is: ${x != y}");
}Output
x > y is: false x < y is: true x >= y is: false x <= y is: true x == y is: false x != y is: true
