ITS CERTIFICATION (JAVA) Review Session  The Information Technology Specialist program allows students to validate entry-level IT skills that employers are looking for. The IT Specialist program is designed for candidates who are considering or have recently begun a career in information technology. Students can earn certification in a variety of IT topics, including software development, database administration, networking and security, mobility and device management, and coding.  Information Technology Specialist Java Examination Java Candidates for this exam are application developers working with Java 6 SE or later, secondary and immediate-post-secondary students of software development, or entry-level software developers.  Information Technology Specialist HTML and CSS Examination Exam Coverage:  Java Fundamentals  Data Types, Variables, and Expressions  Flow Control Implementation  Object-Oriented Programming  Code Compilation and Debugging  Information Technology Specialist HTML and CSS Examination The Exam:  Number of Questions: 40  Question Types: Multiple Choice  Duration: Up to 50 minutes Review Questions  IT Specialist Java Evaluate the following exception: Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: 5 at itsjava.Program.arrayDisplay(Program.java: 31) at itsjava.Program.beginProcess(Program.java: 23) at itsjava.Program.main(Program.java: 18) For each statement select True or False True False The root cause of the exception is in the method beginProcess An error occurred on line 31 Three methods were invoked before the error occurred The stack trace that the exception was caused by a syntax error  IT Specialist Java Evaluate the following exception: Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: 5 at itsjava.Program.arrayDisplay(Program.java: 31) at itsjava.Program.beginProcess(Program.java: 23) at itsjava.Program.main(Program.java: 18) For each statement select True or False True False The root cause of the exception is in the method beginProcess An error occurred on line 31 Three methods were invoked before the error occurred The stack trace that the exception was caused by a syntax error  IT Specialist Java Review the following code: public class Main { public static void main (String args []) throws ArrayIndexOutOfBoundsException { try { int d = 0; int n = 20; int fraction = n / d; int g[] = {1}; g = 100; System.out.println ("The fractional result " + fraction); } catch (ArithmeticException e) { System.out.println("Exception due to "+ e); } catch (RuntimeException e) { System.out.println("Exception due to "+ e); } } } What is the output?

To terminate the outer loop of a nested loop use a _______________ statement. To jump to the next iteration of an inner loop, use a ______________ statement  IT Specialist Java Complete the branching sentences about working with branching statements in Java by selecting the correct words below. unlabeled break labeled break continue To terminate the inner loop of a nested loop, use an unlabeled break statement. The unlabeled break exits the innermost loop it is inside. To terminate the outer loop of a nested loop, use a labeled break statement. A labeled break allows you to specify which loop to terminate by labeling it. To jump to the next iteration of an inner loop, use a continue statement. The continue statement skips the remaining code in the current iteration and moves to the next iteration.  IT Specialist Java You are writing a Java method.
