Pascal/Turbo Pascal - Pascal a Java - Duda de variables y tipos de datos

Tengo el siguiente codigo y necesito pasarlo a Java:



He leido un poco sobre Pascal y su estructura, ya mas o menos como funciona. Pero al momento de pasarlo a Java no hallo muy bien como usar las variables del principio (tCola, tinfo, tPos, ^tNodo, record.... ) y la constante.

Espero me puedan ayudar.

{Espero esto te ayude java no tiene punteros el trabaja como puntero}

Java Pascal
----------------------- -------------------------------
float x, y; var x, y: real;
boolean b; b: boolean;
char c; c: char;
int i, j; i, j: integer;

Java Pascal
----------------------- -------------------------------
int A[] = new int[5]; var A: array[1..5] of integer;
float B[] = {3, 6, 9, 2};
String s = "Hello World!"; var s: string;
... s := 'Hello World';
String t;

Java Pascal
----------------------- -------------------------------
i = i + 1; i := i + 1;
i++;


Java Pascal
------------------------- -------------------------------
++ -- + - ! ( <type> ) n/a n/a + - not n/a
* / % * / div mod
+ - + -
<= >= < > <= >= < >
== != = <>
&& and
|| or
= (assignment) :=


Java Pascal
----------------------- -------------------------------
abs atan cos exp log abs arctan cos exp ln
acos asin ceil floor n/a
max min pow random n/a
rint round n/a
n/a odd ord pred succ trunc
sin sqrt tan sin sqrt tan

Conditionals
Java Pascal
----------------------- -------------------------------
if ( <condition> ) { if <condition> then begin
<statements> <statements>
else { else begin
<statements> <statements>
} end
} end


Java Pascal
----------------------- -------------------------------
for (i=1; i<=n; i++) { for i:=1 to n do begin
<statements> <statements>
} end

while ( <expression> ) { while <expression> do begin
<statements> <statements>
} end
Switch and Break
Java Pascal
----------------------- -------------------------------
switch ( <expression> ) { case <expression> of
case <value1>: <statement1> ; <value1>: <statement1> ;
break;
case <value2>: <statement2> ; <value2>: <statement2> ;
break;
... ...
} end


Java Pascal
----------------------- -------------------------------
<type> <name> (<params>) { function <name> (<params>)
<local variable declarations> <local variable declarations>
begin
<statements> <statements>
return <expression> ; <name> := <expression>
} end;


Java Pascal
----------------------- -------------------------------
"Hello World!" 'Hello World!'
String s = "Hello World!"; var s: string;
... s := 'Hello World!';
String t = "Hello " + s; t := concat('Hello ', s);
i = t.length(); i := length(t);
i = s.indexOf(" "); i := pos(s, ' ');
t = s.substring(6, 10); t := copy(s, 7, 5);
