I have another problem this time if anyone can help with random files i am writting and displaying records from the while but i want to display all records in the file that has data say i have 100 records but only 15 contain user data i want to display only those 15 here is what i have so far. I am getting an exception on line 198.
cont.. james when reading from the scanner brings up errors as random file data is basically on the same line
does java RandomAccesFile class have a method like hasnext with the scanner to scan the random file ?
public static void displayFile()
{
int id = 0;
int age;
String name;
String school;
try
{
Scanner data = new Scanner(new File("Test.txt"));
RandomAccessFile get = new RandomAccessFile("Test.txt","rw");
while(data.hasNext())
{
//store variables from random with random instance
id = get.readInt();
age = get.readInt();
name= get.readUTF();
school = get.readUTF();
if(id!= 0)
{
// display data if id number is not 0
System.out.println("\nId # :" +id);
System.out.println("age :" +age);
System.out.println("Name :" +name);
System.out.println("School :" +school);
}
else if(id == 100)
{
System.out.println("Last record");
}
}// while
}
catch(IOException A)
{
System.err.println("could not display file");
A.printStackTrace();
}
}// end of method
