Design Pattern

System.out.println(“\nChecking “ +
Clientdtls.getName()+ “ (client) loan details.
“);
Clientdtls.checkdetails();
LoanApplication Clientloandtls = new
LoanApplication(“Aqueel”);
System.out.println(“\nChecking “ +
Clientloandtls.getName()+ “ (client) loan
details. “);
Clientloandtls.checkdetails();
}
}

Best example of template design pattern is method overloading and method overriding. For example,

The example illustrated below has an add() method that is a template method. This add() method may take any primitive type numerical value and we can type cast the result according to our requirement.

abstract class AddNumbers {
public abstract double addnumbers(double
d1, double d2);
}
class AddAnyTypeOfNumber extends
AddNumbers{
public double addnumbers(double d1,
double d2) {
return d1 + d2;
}
}

 

 

class TestApplication {
public static void main(String[] args) {
byte b1 = 6, b2 = 2;
short s1 = 4, s2 = 6;
int i1 = 1, i2 = 8;
long l1 = 5, l2 = 9;
float f1 = 14.7f, f2 = 37.9f;
double d1 = 12.7, d2 = 11.2;
AddAnyTypeOfNumber
addanytypeNumber = new
AddAnyTypeOfNumber();
System.out.println(addanytype
Number.addnumbers(d1,d2));
System.out.println((float)addanytype
Number.addnumbers(f1,f2));
System.out.println((long)addanytype
Number.addnumbers(l1,l2));
System.out.println((int)addanytype
Number.addnumbers(i1,i2));
System.out.println((short)addanytype
Number.addnumbers(s1,s2));
System.out.println((byte)addanytype
Number.addnumbers(b1,b2));
}
}
