JAVA中报错i cannot be resolved to a variable

JAVA中报错i cannot be resolved to a variable
import java.util.ArrayList;
public class Test5 {

public static void main(String[] args) {
ArrayList strs =new ArrayList();
strs.add("ABC");
strs.add("DEF");
strs.add("HIJ");
for(int i=strs.size()-1;i>=0; i--);
System.out.println(strs.get(i));
}}

怎么回事啊
