Beginners to ask a question about anonymous classes by value, please everybody help-CodePudding

 public class People {

Public interface Runner {
Void the run (); 
} 
Public void stuAge (int num) {
System. The out. Println (" The age of The Student is "+ num); 
} 

Public static void main (String [] args) {
Runner Runner=new Runner () {
@ Override 
Public void run1 () {
int age=18; 
System. Out.println (" run 10 miles!" ); 
} 
}; 
Runner. The run (); 

People People=new People (); 
People. StuAge (age); 
} 
}

I'd like to know how the age in the anonymous inner class stuAge, predecessors please help look at it

Public class People {

Public interface Runner1 {
Void run1 (); 
Int run2 (); 
} 

Public void stuAge (int num) {
System. The out. Println (" The age of The Student is "+ num); 
} 

Public static void main (String [] args) {
Runner1 runner=new Runner1 () {
int age; 
@ Override 
Public void run1 () {
Age=18; 
System. Out.println (" run 10 miles!" ); 
} 

@ Override 
Public int run2 () {
Return the age; 
} 
}; 
Runner. Run1 (); 

People People=new People (); 
People. StuAge (runner. Run2 ()); 
} 
}

In addition to using this method, are there any other way? If the interface cannot be modified
