Find Min,Max?

Question

Please take a look at my code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.text.DecimalFormat;
import java.text.NumberFormat;
public class StatisticGui extends JApplet
private JButton push;
private JButton calc;
private JTextField tf;
private JTextArea ta;
int push1,push2;
int sum=0,value,sum1=0;
int min,max,range,again;
double average;
double stad,stad1,pass;
public void init()
push1=0;
push=new JButton("Enter Num");
push.addActionListener(new button1());
calc=new JButton("Calc Stats");
calc.addActionListener(new button2());
tf=new JTextField(10);
ta=new JTextArea(16,20);
Container cp=getContentPane();
cp.setBackground(Color.gray);
cp.setLayout(new FlowLayout());
cp.add(tf,BorderLayout.WEST);
cp.add(push,BorderLayout.CENTER);
cp.add(calc,BorderLayout.CENTER);
cp.add(ta,BorderLayout.CENTER);
setSize (400,300);
private class button1 implements ActionListener
public void actionPerformed(ActionEvent event)
String text=tf.getText();
value=Integer.parseInt(text);
min=max=value;
if(value>=0)
push1++;
sum+=value;
sum1+=Math.pow(value,2);
if(value>=50)
push2++;
max = Math.max(max, value);
min = Math.min(min, value);
if(value<0)
do
again=JOptionPane.showConfirmDialog(null,"Invalid Number,Please enter again!");
while(again==JOptionPane.NO_OPTION);
average=(double)sum/push1;
pass= (double)push2 / push1;
stad = sum1/push1 - Math.pow(average,2);
stad1=Math.sqrt(stad);
range=max-min;
private class button2 implements ActionListener
public void actionPerformed(ActionEvent event)
DecimalFormat fmt=new DecimalFormat("0.##");
NumberFormat percent=NumberFormat.getPercentInstance();
ta.append("\nMean:" + fmt.format(average));
ta.append("\nStandDev:" + fmt.format(stad1));
ta.append("\nRange:" +min);
ta.append("\nPercentPass:" + percent.format(pass));
not thing wrong with my code but, i can not find the value of min and max, please help!

Answer 1

String text=tf.getText();
value=Integer.parseInt(text);
min=max=value;So your ''max' and 'min' will be set to 'value' ...
>
if(value>=0)
push1++;
sum+=value;
sum1+=Math.pow(value,2);
if(value>=50)
push2++;
max = Math.max(max, value);
min = Math.min(min, value);And now 'min' and 'max' are calcuelated from in effect
max = Math.max(value, value);
min = Math.min(value, value);
because you have previously set 'min' and 'max' to 'value'.
not thing wrong with my code but, i can not find the
value of min and max, please help!I agree, there is nothing wrong with your code (if you want 'min' and 'max' to be the last values you supplied)!
