How do java public / private and static modifiers affect multiple variables declared on one line?
•
Java
Are the following equivalent?
private static boolean readAllFiles = false,readAllDirs = false; private static boolean readAllFiles = false; private static boolean readAllDirs = false;
If so, do they still have the same modifiers with different values?
private static boolean readAllFiles = false,readAllDirs = true;
Solution
Yes, they are equivalent regardless of their initial values
Here are some test code to demonstrate:
public class TestClass
{
private static boolean readAllFiles = false,readAllDirs = true;
public static void main(String[] args)
{
//these two would result in COMPILE error if both vars were not static
System.out.println("readAllFiles: " + readAllFiles);
System.out.println("readAllDirs: " + readAllDirs);
}
}
public final class TestClass2
{
public static void main(String[] args)
{
//these two DO result in COMPILE error,because both vars are private
System.out.println("TestClass.readAllFiles: " + TestClass.readAllFiles);
System.out.println("TestClass.readAllDirs: " + TestClass.readAllDirs);
}
}
