TestNg--Same "Dataprovider" with different set of data

what is the problem?

when "secondtestcase" is added by coma separator, below error message is displayed

"The method equals(Object) in the type String is not applicable for the arguments (String, String)"


code:

public static Object[][] data(Method d){

Object[][]a= null;

if(d.getName().equals("firsttestcase","secondtestcase")){

a=new Object[2][3];

a[0][0]="User1";
a[0][1]="User1@gmail.com";
a[0][2]="password1";

a[1][0]="User2";
a[1][1]="User2@gmail.com";
a[1][2]="password2";

}else if(d.getName().equals("thirdtestcase")){

a=new Object[2][2];

a[0][0]="Superadmin";
a[0][1]=1;

a[1][0]="admin";
a[1][1]=2;


}

this is wrong
[color=#FF0000:2edl1gcc]if(d.getName().equals("firsttestcase","secondtestcase"))[/color:2edl1gcc]

what are you trying to do here?

Firsttestcase & secondtest case contains SAME set of data

Thirdtestcase contains different set of data.

Iam trying to map all these 3 testcases to SINGLE data provider.

for this reason, i wrote below code

if(d.getName().equals("firsttestcase","secondtestcase"))
