Question

编译JAVA程序时有三个错误，求大神帮忙！

import java.io.*;
class Sum
{
public class void main(String args[])
{
DataInputStream fis=null;
try
{
fis=new DataInputStream(new FileInputStream("myfile.txt"));
String stra=fis.readln();
int a=Integer.parseInt(stra);
String stra=fis.readln();
int b=Integer.parseInt(strb);
int c=a+b;
System.out.println(c.toString());
}
catch(FileNotFoundexception e)
{
System.out.println(e.toString());
}
catch(IOException e)
{
System.out.println(e.toString());
}
catch(NumberFormatException e)
{
System.out.println(e.toString());
}
finally
{
if(fis==null)
{
System.out.println("DateInputStream not open!");
}
else
{
fis.close();
System.out.println("Close DateInputStream!");
}
}
}
}

Answer 1

public class void main(String args[])
应该是
public static void main(String args[])

Answer 2

改为public static void main(String args[])
