我定义了两个类，其中一个类用到类一个类，这两个类同属于一个包，如下：
package nttontology;
import java.util.Comparator;
public class ByValueComparator implements Comparator {
public int compare(Object firstVector, Object secondVector) {
float firstValue = ((Vector) firstVector).getValue();
float secondValue = ((Vector) secondVector).getValue();
if ((firstValue - secondValue) > 0)
return -1;
if ((firstValue - secondValue) < 0)
return 1;
else
return 0;
}
}
************
package nttontology;
public class Vector {
private int index;
private float value;
public Vector(int index, float value) {
this.index = index;
this.value = value;
}
public int getIndex() {
return index;
}
public void setIndex(int index) {
this.index = index;
}
public float getValue() {
return value;
}
public void setValue(float value) {
this.value = value;
}
}
出现以下错误提示：
C:\Tomcat\webapps\mytest\WEB-INF\classes\nttontology\ByValueComparator.java:8:
annot resolve symbol
symbol : class Vector
location: class nttontology.ByValueComparator
float firstValue = ((Vector) firstVector).getValue();
^
C:\Tomcat\webapps\mytest\WEB-INF\classes\nttontology\ByValueComparator.java:10
cannot resolve symbol
symbol : class Vector
location: class nttontology.ByValueComparator
float secondValue = ((Vector) secondVector).getValue();
^
2 errors
望高手指教！！！！！！！！！！！！！！！！
------解决方案--------------------
到C:\Tomcat\webapps\mytest\WEB-INF\classes\nttontology\目录下查看是否存在自定义的Vector.class类
