Answer / ashokmail
By using interface you can do multiple inheritance in java.
Example :
interface student{
public void add();
}
public class clloge implements student{
public clloge(){
}
public void add(){
// Some codes
}
}
public class croom implements student{
public croom(){
}
public void add(){
// Some codes
}
}
Using Interface..
public void uinter {
private student[3] stu ;
public uinter(){
stu[0] = new croom();
stu[1] = new clloge()
stu[2] = new croom();
for(int i=0;i<3;i++)
stu[i].add();
}
}
