Answer 1

Try this code for RMS
public class HighScore extends Canvas {
public Image BackgroundImage;
public Image scoreHeader;
public Image scoreTable;
public Image backImage;
public int key=0;
public MainMidlet mainMidlet;
public StartScreen startScreen;
private int highrecords[];
private String playerName[] = {};
private int score[] = {};
* Constructor creates a new instance of HighScore
* @param mainMidlet is initialized
* @param StartScreen is initialized
public HighScore(MainMidlet mainMidlet,StartScreen startScreen){
setFullScreenMode(true);
this.mainMidlet=mainMidlet;
this.startScreen=startScreen;
try
GameOver.recordStore = RecordStore.openRecordStore("highscore",true);
highrecords = new int[GameOver.recordStore.getNumRecords()];
BackgroundImage=Image.createImage("/icons/bg.png");
scoreHeader=Image.createImage("/icons/highscoreshd.png");
scoreTable=Image.createImage("/icons/highscoretable.png");
backImage=Image.createImage("/icons/back.png");
catch(Exception e)
e.printStackTrace();
* Method paint to used to draw image
* @param g is used to draw
public void paint(Graphics g)
{   String playerNScore = "";
try {
playerName = new String[GameOver.recordStore.getNumRecords()];
score = new int[GameOver.recordStore.getNumRecords()];
catch (Exception e) {
e.printStackTrace();
g.drawImage(BackgroundImage,0,0,g.TOP|g.LEFT);
g.drawImage(scoreHeader,18,18,g.TOP|g.LEFT);
g.drawImage(scoreTable,18,43,g.TOP|g.LEFT);
g.drawImage(backImage,143,199,g.LEFT|g.TOP);
g.setFont( Font.getFont( Font.FACE_PROPORTIONAL,Font.STYLE_BOLD | Font.STYLE_PLAIN, 8 ) );
try{
RecordEnumeration enumhigh = GameOver.enumerate();
int y=65;
int i=0;
while(enumhigh.hasNextElement()) {
playerNScore = new String(enumhigh.nextRecord()).trim();
int pos = playerNScore.indexOf(",");
playerName[i] = playerNScore.substring(0,pos);
score[i] = Integer.parseInt(playerNScore.substring(pos+1));
highrecords=score[i];
i++;
int s =0;
String ss ="";
for(int k=0;k<highrecords.length;k++){
for(int l=k+1;l<highrecords.length;l++){
if(highrecords[k]<(highrecords[l])){

g.drawString(new String(Integer.toString(i)),x,y,g.LEFT|g.TOP);

g.drawString(playerName[k],x,y,g.LEFT|g.TOP);
x+=55;
g.drawString(Integer.toString(highrecords[k]),x,y,g.LEFT|g.TOP);
i++;
y+=15;
} catch(Exception e){
e.printStackTrace();
synchronized public void keyPressed(int keyCode)
key=keyCode;
if(key==-7)
//startScreen.menu_item=0;
