Exam 98-388: Introduction to Programming
using Java

This is an entry level certification that is intended for application developers working with Java. The MTA
exams are targeted at secondary and immediate post-secondary level students of software development,
and other entry-level software developers. The code in the 98-388: Introduction to Programming Using
Java exam, uses Java SE. The syntax used in this exam is compatible with Java 6 SE through the most
recent release.

These Java developers and students require instruction and/or hands-on experience (150 hours) with Java,
are familiar with its features and capabilities, and understand how to write, debug and maintain well-
formed, well documented Java code.

Objective Domain

• Describe the use of main in a Java application.
Understand o Signature of main, why it is static; how to consume an
instance of your own class; command-line arguments
• Perform basic input and output using standard packages.
Fundamentals o Print statements; importing and using the Scanner class

• Evaluate the scope of a variable.
o Declaring a variable within a block, class, method

• Declare and use primitive data type variables.

Work with o Data types include byte, char, int, double, short, long,
float, boolean; identify when precision is lost;
Data Types, initialization; how primitives differ from wrapper object
types such as Integer and Boolean
• Construct and evaluate code that manipulates strings.
o String class and string literals, comparisons,
Expressions concatenation, case and length; String.format methods;
string operators; converting a primitive data type to a
string; the immutable nature of strings; initialization; null

• Construct and evaluate code that creates, iterate, and
manipulates arrays and array lists.

o One- and two-dimensional arrays, including
initialization, null, size, iterating elements, accessing
elements; array lists, including adding and removing
elements, traversing the list

Exam 98-388: Introduction to Programming using Java

Work with • Construct and evaluate code that performs parsing, casting and conversion.
Data Types, o Implementing code that casts between primitive data types, converts primitive types to
equivalent object types, or parses strings to numbers

final to create constants; describe encapsulation

• Declare, implement, and access methods.

o Private, public, protected; method parameters; return type; void; return value; instance
methods; static methods; overloading

• Instantiate and use a class object in a program.

o Instantiation; initialization; null; accessing and modifying data members; accessing
methods; accessing and modifying static members; importing packages and classes

Compile • Troubleshoot syntax errors, logic errors, and runtime errors.

and Debug
o Print statement debugging; output from the javac command; analyzing code for logic
Code errors; console exceptions after running the program; evaluating a stack trace

• Implement exception handling.

o Try catch finally; exception class; exception class types; displaying exception information
