- [轉貼]getting only name of the class Class.getName()
- getting only name of the class Class.getName()
How can i get the name of the class
String.class.getName() returns java.lang.String
I am only interested in getting last part ie only String
The below both ways works fine.
System.out.println("The Class Name is: " + this.getClass().getName());
System.out.println("The simple Class Name is: " + this.getClass().getSimpleName());
Output as below:
The Class Name is: DemoJava.Student
The simple Class Name is: Student
or programmaticaly
String s = String.class.getName();
s = s.substring(s.lastIndexOf('.') + 1);
You can use following simple technique for print log with class name.
private String TAG = MainActivity.class.getSimpleName();
Suppose we have to check coming variable value in method then we can use log like bellow :
private void printVariable(int variable){
Log.e(TAG, "printVariable: "+variable);
}
Importance of this line is that, we can check method name along with class name. To write this type of log.
write :- loge and Enter.
will print on console
E/MainActivity: printVariable: 5
Social.class.getSimpleName()
getSimpleName() : Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous. The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".
To get simple class name without any reference or path use..
String onlyClassName = getLocalClassName();
