Logic error

Course: AP® Computer Science A Shows up in: Unit 1: Using Objects and Methods

A mistake in the algorithm or program that makes it behave incorrectly or unexpectedly. Testing with specific data detects it.

Appears in the course and exam description (CED): 1.1.C.2

A logic error compiles and runs, but the result is wrong. Only testing the program with specific data and comparing the output to the expected outcome reveals it.

int length = 5;
int width = 3;
System.out.println(length + width); // should be length * width
