怎么有这么多的错误

[cdwei80]

//:c03:Assignment.java
//Assignment with objects is a bit tricky
public class Number(){
int i;
}
public class Assignment {
public static void main(String[] args) {
Number n1=new Number();
Number n2=new Numbwe();
n1.i=9;
n2.i=47;
System.out.println("1:n1.i:" + n1.i + ", n2.i:" + n2.i);
n1=n2;
System.out.println("2:n1.i:" + n1.i + ", n2.i:" + n2.i);
n1.i=27;
System.out.println("3:n1.i:" + n1.i + ", n2.i:" + n2.i);
try{
System.in.read();
}catch(Exception e){}
}
}

public class Number()
改称class Number()
一个java文件只能有一个public class

对 对

只能优一个 public class
多余就是错误

[cdwei80]

修改了，还是有好多错误 如下：
cannot resolve symbol
symbol :variable i
location:class Number
System.out.println("1:n1.i:" +n1.i + ",n2.i:" + n2.i);
在n1.i和n2.i的点下有一个尖头
我用的是jdk

[shihongkitty]

class Number{
int i;
}
public class Assignment {
public static void main(String[] args) {
Number n1=new Number();
Number n2=new Number();
n1.i=9;
n2.i=47;
System.out.println("1:n1.i:" + n1.i + ", n2.i:" + n2.i);
n1=n2;
System.out.println("2:n1.i:" + n1.i + ", n2.i:" + n2.i);
n1.i=27;
System.out.println("3:n1.i:" + n1.i + ", n2.i:" + n2.i);
try{
System.in.read();
}catch(Exception e){}
}
}

同上啊，把public class Number(){这句（）去掉，
把Number n2=new Numbwe();中的拼写错误改过来。
