Description:

Project Status:

• Scanning is DONE
  • Scanner is able to scan itsself and all other classes of the project
• Parsing is DONE
• Type checking and error handling is DONE
• Code generation for:
  • arithmetical expressions DONE
  • if/else DONE
  • while DONE
  • try/catch DONE
  • methodcalls (for methods declared within the same class)
  • Strings
  • arrays

• VM finished

• DEBUGGING: (code generation)
  • komplex if statements (ex. if(( i<j || j<k) && p!= 2) etc.)
  • methodcalls with Parameter(s)

• MISSING:
• objects, array of objects

• code generation for:
  • calling mehtods with complex parameters
  • calling methods from other classes

Sample Program

  
public class Scanner {


// Globale Variablen
int [] l = new int [10];
int i = 1;
int j = 4;
int k = 3;


// variablen für if-else Anweisung
int ifWert1 = 10;
int ifWert2 = 23;

// char Varable deklarieren
char c = 'a';


public static void main()
{	
	// boolean Variable deklarieren
	boolean b = true;

// ***** array an einer bestimmten Stelle einen Wert zuweisen 
// ***** wert aus dem Array holen und in eine Variable Speichern 
	
	l[j] = j;
	k = l[j];
	System.out.println("wert des Arrays an der Stelle 'j': " + k);

	
// ***** Aufruf von verschiedenen Unterprogrammen zum Testen
// ***** der Funktionalität von if, else, while
	
	// test einer While-schleife
	whileTest();
	
	// Test von if, else if, else
	ifTest();

	
}

public void whileTest()
{
	System.out.println(" ");
	System.out.println("******* UP: WHILE *******" );
	while ( i < j)
	{
		System.out.println("While-Durchlauf: " + i );
 		i = i + 1;
	}
}

public void ifTest()
{	
	System.out.println(" ");
	System.out.println("******* UP: IF-ELSE *******" );
	if ( ifWert1 < ifWert2)
	{
		System.out.println("Parameter 1: " + ifWert1);
