I have an assignment where i have to read a CSV file containing data with some repeated lines. How to remove the duplicate values and print only the unique values in Eclipse

The data is similar to this:- 

```
1,Ron,1234,ABC,12

2,Harry,4125,DEF,14

3,Kent,1786,GHI,15 

1,Ron,1234,ABC,12

2,Harry,4125,DEF,14

```
