The "Object" class is the topmost class in the class hierarchy. Classes inherit directly from this class by default; all classes inherit from Object directly or indirectly.
Object is the topmost class in the Java Class hierarchy. There is no Class above Object. All classes in Java are implicitly derived from Object.
The basic rule is that the file name should match the name of the topmost public class in the .java file. The names are usually camel case and can contains alphabets and numbers. It should begin only with an alphabet.
Java source files have the .java extension, compiled Java class files have the .class extension.
The actions in a java class are called methods.
without class non of the folder can run so the java program should start in class we can use the class without object in java
What i know is java we will use compiler when it want to get class file(file with .class extension) from java file(file with .java extension).
We can't call a class. We always call a method in java.
Class
All classes in java must inherit from the Object class
To get rid of the Java lang no class deffound error, one must add the class or .jar file which contains this class into the Java classpath. When a Java class is run from the command line, one must add a dot (.)
Yes, the base class for all other Java classes is Object.
An Anonymous class in Java is one that does not have a name. It is usually created inside a class
