1. new 2 & 3. return 4. No. int is a primitive type (for object type Integer), while a variables can hold values (or references) of any type. 5. Just like 1 and 5 are (or can be) literal int values, true and false are literal boolean values. 6. Like true and false, null is also a literal value. It is assigned to any object reference variable that is unassigned. 7. See variables link above (for static). 8. import statements allow access to classes outside your scenario folder that java does not automatically make available (java.lang).

Thank You!!! but I don't understand 2, 3, 7 but I might know what return means. If I do this?does that just set the int test to the int number?

First off, line 1 is totally wrong. It does not have a name; also, usually (at least, for "getter" and "setter" methods), you would not have both a parameter and a return value. A method declaration line consists mainly of three parts -- a return type followed by the method name, followed by a list of parameters within parenthesis separated by commas. Each parameter, if any are given, will be its type followed by its provided name: returnType methodName(<< parameterType1 parameterName1 << , parameterType2 parameterName2 << ... >> >> >>) If the method does not return a value, then the void keyword is used for returnType. Method declaration lines may begin with one or more modifiers Access modifiers: public protected, or private; Static modifier: static (makes method a class method instead of an instance method) Final modifier: final; (prevents overriding the mehod) A normal "getter" and "setter": Basically, return means to exit the method and resume execution of the method calling this method. If a value is returned, it must be dealt with on the calling line of code or it will be lost.

1. do is a program flow looping operation. Code within its brackets will repeat continuously until a break statement is encountered or until a while conditional expression fails. 2. long is a primitive type meant for quite large integer values. 3. double is also a primitive type meant for modest non-integer values. 4. while(conditionalExpression) controls looping. It can be used alone to start a loop with the condition being checked BEFORE each pass or it can be appended to a do loop to check the condition AFTER each pass. 5. final modifies a method so that it cannot be overridden or modifies a variable to make it a constant (its value cannot be changed). Note that as an object reference, the object can still be modified, but it cannot be replaced by another object.

Thank you but wouldn't do the same thing as "do"?

The act method is executed once per act cycle for the active world and all actors in the world. A (do-)loop executes until it finishes. Nothing else is happening in the meantime.

Thank you so much!!!
