What are If Statements ?

An If statement is a way in Java where a piece of code gets executed if the conditions are true. Below is an example.

If ( 33 > 4) {

System.out.println ( “This statement is true!” );

}

This statement is true gets printed because 33 > 4 is true.

 

If the statement in the parenthesis is false, the code will not get executed, but the code in the Else statement will. Here is an example.

If (2 + 3 = 6) {

System.out.println (” This statement is true”);

}

Else {

System.out.println (“The statement was false”);

}

The statement was false will be printed because 2 + 3 = 6 is not true.

Else If

You learned about if and else statements, but there can be many if statements. Look at the example below.

If (3 > 5) {

System.out.println ( “Your not so great at math.”);

}

Else If (3 > 4) {

System.out.println(“Still not so great at math.”)

}

Else If (3 == 3) {

System.out.println(“Getting closer. . .”);

}

else {

System.out.println (“None of the math statements are true.”);

}

If the if statement isn’t true, it follows the else If statements. If the else if statement isn’t true, it follows the next one. If  none of the statements are true, it follows the else statement.

Getting closer. . . will get printed because the statement 3 == 3 is true.
