It appears there may be a problem or two with DataInputStream formatting? The following code example does not generate the expected results.

import java.lang.*;
import java.io.*;

class test {
public static void main (String arg[]) throws IOException {
DataInputStream myin=new DataInputStream(System.in);
PrintStream myout=new PrintStream(System.out);
float price;
int weight;
String desc;

price = myin.readFloat();
myin.readChar();
weight = myin.readInt();
myin.readChar();
desc = myin.readLine();

System.out.print(price);
System.out.print(" ");
System.out.print(weight);
System.out.print(" ");
System.out.print(desc);
System.out.println();
System.out.flush();
System.out.println( price+":"+weight+":"+desc);
myout.println(price+":"+weight+":"+desc);
}
}

**** or maybe not. Here is how it should be done; maybe this is a documentation problem.


public class IOtest
{
   public static void main (String arg[]) throws IOException
   {
      int maxBuffer = 1024;
      int bytesRead;
      byte bytes[] = new byte[maxBuffer];
      String sTemp;
      float price;
    int weight;
      String desc;

      System.out.print("Enter float: ");
      System.out.flush();
      bytesRead = System.in.read(bytes, 0, maxBuffer);
      sTemp = new String(bytes, 0, 0, bytesRead);
      price = Float.valueOf(sTemp).floatValue();
  
      System.out.print("Enter integer: ");
      System.out.flush();
      bytesRead = System.in.read(bytes, 0, maxBuffer);
      sTemp = new String(bytes, 0, 0, bytesRead);
      weight = Integer.parseInt( sTemp.trim() );

      System.out.print("Enter some text: ");
      System.out.flush();
      bytesRead = System.in.read(bytes);
      desc = new String(bytes, 0, 0, bytesRead);

      System.out.println();
      System.out.print( "Price: " + price );
      System.out.print( " Weight: " + weight );
      System.out.println( " Description: " + desc );
   }
}
