Hi Friend,

Try the following code:

import java.io.*;
import java.awt.*;
import java.util.*;
import javax.swing.*;
import java.awt.event.*;

public class SearchName extends JFrame{
static String name;
static String age;
public SearchName(){}
public SearchName(String name,String age){
this.name=name;
this.age=age;
}
public String getName(){
return name;
}
public String getAge(){
return age;
}
public static void main(String []args){
SearchName search=new SearchName();
JButton button=new JButton("Search");
JPanel panel=new JPanel();
panel.add(button);
search.add(panel);
search.setSize(300,60);
search.setVisible(true);
ActionListener actionListener = new ActionListener() {
public void actionPerformed(ActionEvent actionEvent) {
String n=JOptionPane.showInputDialog(null,"Enter name");
try{
FileInputStream fstream = new FileInputStream("studentRecord.txt");
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
ArrayList list=new ArrayList();
while ((strLine = br.readLine()) != null){
list.add(strLine);
}
Iterator itr;
for (itr=list.iterator(); itr.hasNext(); ){
String str=itr.next().toString();
String [] splitSt =str.split(" ");
String id="",name="",age="";
for (int i = 0 ; i < splitSt.length ; i++) {
id=splitSt[0];
name=splitSt[1];
age=splitSt[2];
}
ArrayList<SearchName> alist = new ArrayList<SearchName>();
alist.add(new SearchName(name,age));
for (SearchName s : alist){
if(n.equals(s.getName())){
System.out.println("Name Age ");
System.out.print(s.getName()+" " +s.getAge());
}
}
}
}
catch(Exception e){}
}
};

button.addActionListener(actionListener);
}
}

Thanks

Thanku
