Why we define constructor in abstract class in java when we can't initialized it abstract class. Or how constructor of abstract class can used. Give an example
publi
c abstract class TestR4R{
public TestR4R(){
}
public TestR4R(String str1 , String str2)
{
}
}
class
Test extends TestR4R{
public Test(){
super();
}
public Test(String str1 , String str2){
super(str1,str2);
