Java Foundations Certification Exam Topics

Using Decision Statements

• Use the decision making statement (if-then and if-then-else)

• Use the switch statement

• Compare how == differs between primitives and objects

• Compare two String objects by using the compareTo and equals methods

Working with Java Operators

• Use basic arithmetic operators to manipulate data including +, -, *, /, and %

• Use the increment and decrement operators

• Use relational operators including ==, !=, >, >=, <, and <=

• Use arithmetic assignment operators

• Use conditional operators including &&, ||, and ?

• Describe the operator precedence and use of parenthesis
