In this blog, I will show some sample codes about If-Else Statements in Java. The If-Else Statements is used to test the condition of the given statement. Whether the output is True or False. We can also test multiple condition. I will demonstrate some basic but straight forward in applying the If-Else Statement.
Java supports logical condition from mathematics:
- Less than : a < b
- Less than or equal to: a <= b
- Greater than: a > b
- Greater than or equal to: a >= b
- Equal to a == b
- Not Equal to: a != b.
Java has the following conditional statements:
- If Statement
– This statement is used to specify the code if the condition is true.
Syntax:
if (condition) {
// block of code to be executed if the condition is true
}
Sample Code:
Output:
- Else Statement
– This statement is used to specify the code if the condition is false.
Syntax:
if (condition) {
// block of code to be executed if the condition is true
} else {
// block of code to be executed if the condition is false
}
Sample Code:
Output:
The statement is True:
The statement is False:
- Else-IF statement
– This statement is used to specify a new condition if the first condition isfalse.
Syntax:
if (condition1) {
// block of code to be executed if condition1 is true
} else if (condition2) {
// block of code to be executed if the condition1 is false and condition2 is true
} else {
// block of code to be executed if the condition1 is false and condition2 is false
}
Sample Code:
Output:
-If the condition 1 is True.
-If condition1 is false and condition2 is true.
-If condition1 is false and condition2 is false.
