StringBuffer and StringBuilder
package org.day.strings;
import java.io.BufferedReader;
public class Test { public static void main(String[] args) { StringBuffer sb1 = new StringBuffer(); sb1.append("Daya");
StringBuilder sbu2 = new StringBuilder();
sbu2.append("Daya");
System.out.println(sb1.equals(sbu2));
/* why sb1 and sbu2 are not equal */
}

it is coz whenever objects are created with new operator, a new memory is allocated and hence new reference id generated;
so sb1 and sbu2 will get different refence ids;
here equals method of Object class will work it compares two refernce id which are not equal.
