When writing variable declarations, you need to consider: | When writing variable declarations, you need to consider: | ||

| + | When you are done, put the code and the results from running it into a document, then print it for me to grade. You can also show me what you've done at the computer any time. Do not get stuck: you should be able to get this done today if you persevere. If you can't then finish it for homework. | ||

| + | * How to translate an English description into a field or method. | ||
| + | * You don't need to know the context to program something. | ||
| + | * How to follow instructions closely and completely. | ||
| + | * How to use a method more than once with different arguments. | ||
| + | * How to make a method and use it more than once rather than duplicate code. | ||
| + | * How to make and use arrays. | ||
| + | * How to initialize Strings and arrays of Strings. | ||
| + | * Returned values must match the return type. | ||
| + | * The difference between int and double, especially for division. | ||
| + | * How to pick meaningful names for methods and variables (fields and local variables.) | ||
| + | * The meaning of static, public and private can still be a mystery. | ||
| + | * Pitfall: using the same name for a field and an argument or local variable. Don't do it. | ||
| + | * We can write a large, awesome program that does real stuff! | ||
