在编译的时候遇到could not find symbol，该怎么做

Question

```java
public class ContinueFor{
    public void main(String[]args){
        int sum=0;
        for(int i=1;i<=5;i++);{
        if(i%2==0){
            continue;//跳转到改变变量i++处
        }
        sum+=i;


         }
           System.out.println("the sum is"+sum);
    }

}

ContinueFor.java:5: error: cannot find symbol
        if(i%2==0){
           ^
  symbol:   variable i
  location: class ContinueFor
ContinueFor.java:6: error: continue outside of loop
            continue;//跳转到改变变量i++处
            ^
ContinueFor.java:8: error: cannot find symbol
        sum+=i;
             ^
  symbol:   variable i
  location: class ContinueFor

Answer 1

//这里为何多个分号?
for(int i=1;i<=5;i++);{
   //                           ^
        if(i%2==0){
            continue;//跳转到改变变量i++处
        }
        sum+=i;
