How to store values from excel to some collection in java [closed]

Answer 1

You should use Object Oriented approach to create entities. Create a class representing your excel data row, lets say called Records and then put the objects of this class in a Hashmap against username as key. Here is sample class :

public class Record {

    private String methodName;
    private String statusCode;
    private String user;
    private String password;

    public String getMethodName() {
        return methodName;
    }

    public void setMethodName(String methodName) {
        this.methodName = methodName;
    }

    public String getStatusCode() {
        return statusCode;
    }

    public void setStatusCode(String statusCode) {
        this.statusCode = statusCode;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}

Define a collection to store the records as

Map<String, Record> recordsMap = new <String, Record>HashMap();

Read the excel file, create a record for each row and save in this collection. It should be easy and quick to retrieve the records from the map.
