public class S1 extends JApplet implements ActionListener {
final int WON = 0, LOST = 1, WON2 = 2;

boolean firstAnswer = true;
int a=0;
int b=0;
int gameStatus ;
JLabel inputLabel, printLabel;
JTextField inputField;
public void init()
{

Container container = getContentPane();

container.setLayout( new FlowLayout() );

inputLabel = new JLabel( "input one number" );

container.add( inputLabel );

inputField = new JTextField( 10 );

container.add( inputField );

printLabel= new JLabel("Guess a number between 1 and 2");

container.add(printLabel);

inputField.addActionListener( this );
}
public void actionPerformed( ActionEvent actionEvent )
{

b = Integer.parseInt( inputField.getText() );

inputField.setText( "" );

if ( firstAnswer ) {

int a = 1 + ( int ) ( Math.random() * 2 );
if (a==b)

gameStatus = WON;

else{

gameStatus = LOST;

}

}

else{

if (a==b){

gameStatus = WON2;

}

else{

gameStatus = LOST;

}

}

displayMessage();
}
public void displayMessage()
{

if (gameStatus == WON)

showStatus("Too high .Try again");

if (gameStatus == WON2){

showStatus("Congratulations.You guessed the number!");

firstAnswer=true;

return;}

if (gameStatus == LOST){

showStatus("Too low . Try again");

firstAnswer=false;

return;}

}
}
怎么每次我输入了一个数与随机产生的数不同时，如我输入1，随机产生2.就不能再继续运行的？就是以后不管输入什么数，都只能显示"Too low . Try again"这个的？？帮忙帮忙！！谢谢！！
我就是想知道，为什么猜错之后，不能在重新运行一次！！

当然了关键是这里，int a = 1 + ( int ) ( Math.random() * 2 );random是产生0到1之间的double值，乘2去整加1后，a要么是1，要门是2，不可能和b的0相等的，所以gameStatus = LOST; 出现你的结果...
