toString() method implementation

Implementing toString() method which displays all the property names along with values will be very much helpful while debugging the application. But implementing toString() method for a java class containing lot of properties is painful.

For implementing toString() method we can use any of the following easy approaches:

1. If you are using eclipse 3.5 or above:
a)Right Click on the file.
b)Select source
c)Select generate toString()
d) Choose what are all the fields you want to display then OK

It will create a toString() method something like this:
@Override
public String toString()
{
return "User [address=" + address + ", id=" + id + ", name=" + name+ "]";
}

2)Use commons-lang API "ToStringBuilder"
@Override
public String toString()
{
return ToStringBuilder.reflectionToString(this);
}

This will display the object as
com.javautils.test.User@578ceb[id=1,name=siva,address=hyd]
