assignment problem help needed

[tiggz1980]

Hi all i am currently doing an assignment and struggling like mad all i need to do is create a right angled triangle out of asterisks such as

*
**
***
****
*****

it has the size set to 5 and the orientation set to up all i need to know is how to get the public instance method called generate row to work correctly any help would be appreciated i am drowning i cannot get to grips with this at all.

the code for the method is below it should use a loop and concatenation to produce the triangle any help on this would be grateful.

import ou.*;

/**
* Class Triangle - instances model triangles as rows of asterisks
*
* M255 Course Team
* Version 1.0
*/
public class Triangle
{
/* instance variables */
int size; // the size of the triangle; an integer between 2 and 10 inclusive
String orientation; // either "up" or "down"
String asterisk;

/**
* Constructor for objects of class Triangle.
*/
public Triangle()
{
super();
this.size = 5;
this.orientation = "up";


}



/* instance methods */

/**
* Return the orientation of the triangle.
*/
public String getOrientation()
{
return this.orientation;
}

/**
* Return the size of the triangle.
*/
public int getSize()
{
return this.size;
}

/**
* Generates a row of Asterisks
*/
public String generateRow()
{
asterisk = "";
aSize = Integer.parseInt(return this.size);
for (int num = 1; num <= asize; num++)

asterisk = asterisk + "*";

System.out.prinln(asterisk);
}

}

Try the following piece of code. It will draw downwards. Make a try for the upward one also.
import java.io.*;

public class DrawTriangle
{
private int rows;


public int getInteger()throws IOException
{

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
return Integer.parseInt(br.readLine());
}

public void generateTriangle()
{
for(int i=1;i<=rows;i++)
{
String currentRow="";
for(int j=1;j<=i;j++)
{
currentRow = currentRow +"*";
}
System.out.println(currentRow);
}
}

public void getNoOfRows()throws IOException
{
System.out.print("Enter no of rows:");
rows = getInteger();
}


public static void main(String args[])throws IOException
{

DrawTriangle draw = new DrawTriangle();
draw.getNoOfRows();
draw.generateTriangle();
}
}

First welcome to the Java Forums!

Second, it seems you're going to too much trouble to get the program functioning as it should. There's a recent Triangle question in the forums, see if that helps.
