notes for teaching basic Java class

1. Java notes
Language info

2. For Loops
for (int i = 1; i <= stop; i++)
{
//do something
}

3. Create and Assign Variables
String zipcode = “90210”;
//the current zipcode is 90210

4. Increment Variables
int age = 38;
age += 1;
//also can increment
age++;

5. Conditionals - If
int test = 0;
if (test < 0)
{
//do something
}

6. Conditionals – If / Else
int test = 0;
if (test < 0)
{ //do something }
else
{ //do something else }

7. Create a Method
public static void doIt (String s )
{
//do something
}

8. Use a Method
String s = “hello”;
doIt ( s );

9. To view a Value -- Getters
GetPenColor ( );
GetPenWidth ( );
GetSpeed ( );

10. To Change a Value -- Setters
SetPenColor (Colors.Reds.Red);
SetPenWidth ( 5 );
SetX ( 10 );

11. Arrays
int array [ ] = new int [ 1 ];
int array [ ] = { “one” };
array [ 1 ] = “one”;
