3,377 PointsCompiler error unclear... don't see what the problem is.
Compiler error reads as such: ./com/example/BlogPost.java:4: error: cannot find symbol import java.util.Arraylist; ^ symbol: class Arraylist location: package java.util ./com/example/BlogPost.java:60: error: cannot find symbol List results = new ArrayList(); ^ symbol: class ArrayList location: class BlogPost Note: JavaTester.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 2 errors
This is truly a mind boggling error considering my code for using List and ArrayList matches the Java API in Oracle as well as the instructors code in Workspace.
package com.example;
import java.io.Serializable;
import java.util.Arraylist;
import java.util.Arrays;
import java.util.Date;
import java.util.List;
public class BlogPost implements Comparable<BlogPost>, Serializable {
private String mAuthor;
private String mTitle;
private String mBody;
private String mCategory;
private Date mCreationDate;
public BlogPost(String author, String title, String body, String category, Date creationDate) {
mAuthor = author;
mTitle = title;
mBody = body;
mCategory = category;
mCreationDate = creationDate;
}
public int compareTo(BlogPost other) {
if (equals(other)) {
return 0;
}
return mCreationDate.compareTo(other.mCreationDate);
}
public String[] getWords() {
return mBody.split("\\s+");
}
public String getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
public String getBody() {
return mBody;
}
public String getCategory() {
return mCategory;
}
public Date getCreationDate() {
return mCreationDate;
}
//Let's add a method that returns a list of all links in the body of the document.
//All words that start with http should be considered links. Name it getExternalLinks.
//NOTE: Remember to import the needed classes from java.util. HINT: We already made the getWords method, we should use it!
public List<String> getExternalLinks()
{
List<String> results = new ArrayList<String>();
for (String word : getWords())
{
if (word.startsWith("http"))
{
results.add(word);
}
}
return results;
}
}
