有段代码想了好久都不懂.请各位帮忙一下

public class P622 extends JApplet implements ActionListener {
JTextField inputField, resultField,t1,t2;
JLabel inputLabel, resultLabel;


public void init()
{
inputLabel = new JLabel( "Enter the integer(1-99999):" );
inputField = new JTextField( 5 );
inputField.addActionListener( this );

resultField = new JTextField( 20 );
resultLabel = new JLabel( "Result" );
resultField.setEditable( false );

Container container = getContentPane();
container.setLayout( new FlowLayout() );
container.add( inputLabel );
container.add( inputField );
container.add( resultLabel );
container.add( resultField );


}

public void actionPerformed( ActionEvent actionEvent )
{
int inputNumber =
Integer.parseInt( inputField.getText() );

if ( inputNumber <= 99999 && inputNumber >= 1 )
displayDigits( inputNumber );

}

public int quotient( int a, int b )
{
return a / b;
}

public int remainder( int a, int b )
{
return a % b;
}

public void displayDigits( int number )
{
int divisor = 1, digit;
String result = "";

for ( int i = 1; i < number; i *= 10 )
divisor = i;

while ( divisor >= 1 ) {
digit = quotient( number, divisor );

result += digit + " ";
number = remainder( number, divisor );
divisor = quotient( divisor, 10 );
}

resultField.setText( result );

}



}



public void displayDigits( int number )
{
int divisor = 1, digit;
String result = "";

for ( int i = 1; i < number; i *= 10 )
divisor = i;

while ( divisor >= 1 ) {
digit = quotient( number, divisor );

result += digit + " ";
number = remainder( number, divisor );
divisor = quotient( divisor, 10 );
}

resultField.setText( result );

}
这个方法中 WHIILE 调用 quotient ,remainder方法.这一部分不太理解是怎么计算的.

大概看了下。。

quotient是求两个数之商，remainder求两个数之余。

displayDigits是让一个数转换成字符串。它是让这个数从最高位开始，一位一位地输出数字。。


建议使用eclispe调试工具好好分析逻辑。。。
