you should use java.io.File;
i paste some code you can refer to :
import java.io.*;
public class PushBack {
public static void main(String[] a) throws IOException
{
FileReader fr=new FileReader("test.txt");
PushbackReader pbr=new PushbackReader(fr,20);
//------------------------------------------------------ ---------
char[] arr=new char[15];
pbr.read(arr,0,arr.length);
for(int i=0;i<arr.length;i++){
System.out.println(arr[i]);
}
System.out.println("------------");
//--------------------------------------- ------------------------
char[] app={'f','f','f','f'};
pbr.unread(app,0,app.length);
for(int i=0;i<app.length;i++){
System.out.println(app[i]);
}
System.out.println("------------");
//--------------------------------------- ------------------------
char[] acc=new char[4];
pbr.read(acc,0,acc.length);
for(int i=0;i<acc.length;i++){
System.out.println(acc[i]);
}
System.out.println("------------");
}
}
maybe above code is not exact to your question
but you can understand how to read and write from a file
through it
