Object-Oriented Programming (Narva College) 2018/19 spring

Before session 2

Program Control Statements. Loops. Methods. Arrays.

Objectives:

After completing the session, a student can:

• explain the following terms: program control statements, loops, signature of a method, formal and actual parameters, types of methods, a return statement;
• control program flow using if statements and nested if statements;
• choose the appropriate repetition control statement for a given task and implement it in a program using while, do-while or for (nested) statements;
• define simple static methods with formal parameters;
• invoke static methods with actual parameters;
• define methods with a return value;
• use method overloading;
• describe the essence of arrays in programming;
• declare a one- and multidimensional array;
• declare, create, and initialize a one- and multidimensional array using an array initializer;
• access array elements using indexes;
• simplify programming using the for each loops;
• retrieve data from the command line and convert them into an appropriate data type.
