I'm supposed to prompt the user to enter the second player's name using a print statement and scanner. I thought I had it set up correctly but it prints out the prompt and then moves on, never allowing me to actually enter a name.

 It's kinda hard for me to look at this without seeing an assignment sheet. Why are you using player2.setPlayerName(p2Name);
this statement? 
Sorry. | Code: | public class Player
{ private String name;
private int score1;
private int score2;
private int score3;
public Player()
{
name = "No Name";
score1 = 0;
score2 = 0;
score3 = 0;
}
public int getScore1()
{
return score1;
}
public int getScore2()
{
return score2;
}
public int getScore3()
{
return score3;
}
public String getPlayerName()
{
return name;
}
public void setPlayerName(String _name)
{
name = _name;
}
public void setScore1(int _score1)
{
score1 = _score1;
}
public void setScore2(int _score2)
{
score2 = _score2;
}
public void setScore3(int _score3)
{
score3 = _score3;
}
public boolean validateScore(int score)
{
if((score >= 0) && (score <= 100))
{
return true;
}
return false;
}
public int calcTotal()
{
return score1+score2+score3;
}
public double calcAverage()
{
int total = calcTotal();
return (double)total/3.0;
}
public int calcHighScore()
{
int high = score1;
if(score2 > high)
{
high = score2;
}
if(score3 > high)
{
high = score3;
}
return high;
} } |

Can you post it with indents? Hella hard to troubleshoot when it's like that. Also, if I were writing such a program, I'd implement a method called getInfo() or something within Player.java that input a Player object and prompted the user for and properly stored all of the information. It'd shorten the amount of code significantly, and make troubleshooting much easier (if required at all). Then your main would look something like Player player1 = new Player();
Player player2 = new Player();
player1.getInfo();
player2.getInfo();
System.out.println(player1);
System.out.println(player2); If you put a toString() method in Player.java, then you can do the above. System.out.println(player1) will print out the value of player1.toString() if such a method exists, also reducing the redundancy of your code. My bad if this is hella useless information. I dunno what's wrong with your code because reading it is a bitch and it's difficult to find problems with it in its current, unindented form. So yeah. You in AP CS? It's teh shit I'm in that class right now ...
