// spring buffer will evaulate to false while comparing two strings.But in the above tutorial it is said as true.

public static void main(String[] args) {


StringBuffer sb = new StringBuffer("hello1");
StringBuffer sb1 = new StringBuffer("hello1");



// this would be false because String buffer does not have
// an equals method and the control would pass on to StringBuffer
// equal method.
// The Objects equal method will not know it wwere just two
// string , they are just two objects.
if(sb.equals(sb1)){
System.out.println("String buffer equals");
}else
System.out.println("String buffer not equals");



// == equal compares the memory location and hence since
// they are two different objects it will be false.
if(sb == sb1){
System.out.println("String buffer == equals");
}else
System.out.println("String buffer not== equals");


}
