Also called: decision making, conditional statement
Course: AP® Computer Science A Shows up in: Unit 2: Selection and Iteration
An algorithm building block in which a true or false decision chooses how the execution of the algorithm proceeds.
Appears in the course and exam description (CED): 2.1.A.12.1.A.22.1.A.32.3.A.1
Selection is one of the three building blocks of algorithms, with sequencing and repetition. In Java, selection statements (if, if-else, if-else-if) change the sequential execution of statements.
int temperature = 31;
if (temperature > 25) {
System.out.println("Wear shorts");
}
Output:
Wear shorts Learn it properly, with a checkpoint 2.1 Algorithms with Selection and Repetition
