Write an abstract class of the Java method to calculate the user to enter the average of the three Numbers,

CodePudding user response:

Then you will be a class definition for the abstract, afterward again write a calculation inside draw the value of the method is not good

CodePudding user response:

 import Java. Math. BigDecimal; 

Public class Test1 {

The static abstract class AbsDigitalProcessor {

Public void doProcess (int a, b int, int) c {
BigDecimal result=calculate (a, b, c); 
System. The out. Println (result. ToPlainString ()); 
//get the result to do something 
} 

Protected the abstract BigDecimal calculate (int a, b int, int) c; 
} 

Static class AvaDigitalProcessor extends AbsDigitalProcessor {

@ Override 
Protected BigDecimal calculate (int a, b int, int) c {
Return new BigDecimal ((a + b + c)/(3); 
} 
} 

Static class CountDigitalProcessor extends AbsDigitalProcessor {

@ Override 
Protected BigDecimal calculate (int a, b int, int) c {
Return new BigDecimal (a + b + c); 
} 
} 

Static class SubDigitalProcessor extends AbsDigitalProcessor {

@ Override 
Protected BigDecimal calculate (int a, b int, int) c {
Return new BigDecimal (a - b - c); 
} 
} 

Public static void main (String [] args) {
New AvaDigitalProcessor (.) doProcess (1, 2, 3); 
New CountDigitalProcessor (.) doProcess (1, 2, 3); 
New SubDigitalProcessor (.) doProcess (1, 2, 3); 
} 

}

Abstraction is the abstract
