j_builder 使用问题

[davidjian]

第一次使用j_builder 时如何使用

比方说 做一个输出的程序的具体步骤

[davidjian]

package com.borland.samples.java;
import java.util.HashMap;

public class java1
{
static HashMap statistic(String strA)
{
int j;
HashMap hChars= new HashMap();
for (int i=0;i<strA.length();i++ )
{
String word=strA.substring(i,i+1);
//if((Character)word.charValue()!=new Character(' '))
if(hChars.get(word)!=null)

{ j = ((Integer) hChars.get(word)).intValue();
hChars.put(word, new Integer(j+1)) ;
}
else
hChars.put(word,new Integer(1));
}

return(hChars);
}

public static void main(String[] args)
{
String str="this is a apple!";
HashMap hChar1 = statistic(str);
System.out.print(hChar1);
}

}
这是我的程序
C:\JBuilder6\jdk1.3.1\bin\javaw -classpath "C:\Documents and Settings\shenjian\jbproject\java\classes;C:\JBuilder6\jdk1.3.1\demo\jfc\Java2D\Java2Demo.jar;C:\JBuilder6\jdk1.3.1\jre\lib\i18n.jar;C:\JBuilder6\jdk1.3.1\jre\lib\jaws.jar;C:\JBuilder6\jdk1.3.1\jre\lib\rt.jar;C:\JBuilder6\jdk1.3.1\jre\lib\sunrsasign.jar;C:\JBuilder6\jdk1.3.1\lib\dt.jar;C:\JBuilder6\jdk1.3.1\lib\htmlconverter.jar;C:\JBuilder6\jdk1.3.1\lib\tools.jar" junit.textui.TestRunner Tools

这是报的错
