Need test test code to test class Concert and getArtist.

error: method getArtist in class Concert cannot be applied to given types
required: java.lang.String
found: no arguments
reason: actual and formal argument lists differ in length

public Concert()
{
    int m = 9;
    int d = 8;
    int y = 2019;
    String a = new String("Jonas Brothers"); 
    String v = new String("Van Andel Arena");
    int totalSales = 0;
    getArtist(a);
}

public Concert (int m, int d, int y, String a, String v) 
{
    m = 9;
    d = 8;
    y = 2019;
    a = new String("Jonas Brothers"); 
    v = new String("Van Andel Arena");
    int totalSales = 0;
 }

public String getArtist(String a)
{
    return a;
}

    Concert concert = new Concert();

  • What line gives the error? Please label it in your code. – FailingCoder Oct 02 '19 at 23:56

    I think that you need to learn what `fields` are. If you declared a variable within a method or constructor or other code block, it is limited in scope to that code block. – Scary Wombat Oct 03 '19 at 00:05

    Also if you have a method like `public String getArtist(String a)` it means that it is expecting a paramater, so code like `concert.getArtist()` will not compile. – Scary Wombat Oct 03 '19 at 00:06

GetArtist method in Concert class is expecting a parameter which is missing in unit test calling code. Hence compilation fails.
