overridding:
same method name and same signature.
import java.io.*;
class sum
{
int a=10,b=15;
void sum()
{
int sum=a+b;
System.out.println("sum is:"+sum);
}
}
class sum1 extends sum
{
int c=20;
void sum()
{
int sum1=a+b+c;
System.out.println("sum1 is:"+sum1);
}
}
class override{
public static void main(String[] arg){
sum s=new sum();
s.sum();
sum1 s1=new sum1();
s1.sum();
}
}

over loading:
method name same but different signature.
class sum{
void add(int a,int b){
}
class sum{
void add(string s1,string s2){
}
