Call String methods for a String class
Explain the importance of APIs, documentation and packages in Java

Enduring Understandings

This lesson builds toward the following Enduring Understandings (EUs) and Learning Objectives (LOs). Students should understand that…

EU Var-1 To find specific solutions to generalizable problems, programmers include variables in their code so that the same algorithm runs using different input values. (LO’s 1.E, 1.D)
EU Mod-1 Some objects or concepts are so frequently represented that programmers can draw upon existing code that has already been tested, enabling them to write solutions more quickly and with a greater degree of confidence. (LO’s 1.G, 1.F, 1.C)
