Cannot find symbol in Locale class

I'm having some trouble with building my code, and it stems from objects from the Locale class in my tests. Here is a quick mock-up of how my test class looks like:

import java.util.Locale;

public class myTest {

    public class test1() {
        Locale locale = new Locale("");
        locale = Locale.getDefault(Locale.Category.DISPLAY);
        ....
    }

    public class test2() {
        Locale locale = new Locale("");
        locale = Locale.forLanguageTag("testController1");
        ....
    }
}

Now, for the first test, I get there error:

[6376,41] cannot find symbol
[ERROR] symbol  : variable Category
[ERROR] location: class java.util.Locale

And for the second test, I get:

[6675,23] cannot find symbol
[ERROR] symbol  : method forLanguageTag(java.lang.String)
[ERROR] location: class java.util.Locale

I'm not sure why I am getting these errors. In the first code, the locale object was instantiated as Locale local = Locale.forLanguageTag("testController1");, and I thought that was the issue, but I guess not.

EDIT: Could somebody tell me why this question was voted down? I did my research, and most answers point me to an object that is out of scope. I pretty much made sure my object is in scope, so I am still unclear.
