br.readLine()

[Clarabelle Smith]

Hi,
I have been trying to get this to compile, and it will not. How come? It keeps telling me something is wrong with my readLine. Ugh.
package java192.project5;
import java.io.*;
import java.util.*;
public class SendPackage
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
{
System.out.println("Please enter the weight, shipping method - A, T or M - "
+ "and type the word 'insured' if insurance is desired.");
System.out.println("Each item needs to be entered on ONE line followed "
+ "by a space.");
int tokenCnt;
int t = 0;
String strInput = br.readLine();
StringTokenizer st = new StringTokenizer(strInput);
tokenCnt = st.countTokens();
String[] strTokenArray = new String[tokenCnt];
if (st.hasMoreTokens())
{
strTokenArray[t] = st.nextToken();
++t;
}
}
}
Thx.

Something is wrong? Why not tell us what exactly is wrong instead of making us copy your code and compile it? Here is the actual error:
SendPackage.java:16: unreported exception java.io.IOException; must be caught or declared to be thrown
String strInput = br.readLine();
^
1 error

So what is the problem? The error says that the readLine() might throw an IOException which must be caught! So catch it!

try {
    // stuff that throws exceptions;
} catch (IOException io) {
    // do stuff with exception;
}

You can either catch it as Thomas said, or you can declare it to be thrown.

For example:
public static void main( String[] args ) throws IOException

Also, formatting your code makes it easier to read.

package java192.project5;
import java.io.*;
import java.util.*;
public class SendPackage 
{
    BufferedReader br = new BufferedReader( new InputStreamReader( System.in ) );
    
    {
        System.out.println("Please enter the weight, shipping method - A, T or M - " + 
                "and type the word 'insured' if insurance is desired.");
        System.out.println("Each item needs to be entered on ONE line followed " + 
                "by a space."); 
        int tokenCnt ;
        int t = 0;
        String strInput = br.readLine(); 
        StringTokenizer st = new StringTokenizer( strInput );
        tokenCnt = st.countTokens();
        String[] strTokenArray = new String[ tokenCnt ]; 
        
        if ( st.hasMoreTokens() )
        {
            strTokenArray[ t ] = st.nextToken();
            ++t ;
        }
    }
}

Thank you BOTH for your help. I didn't notice when I pasted my code into here, it took away the formatting. I will make sure to add that back in for any future posts I may make.
