    <p>How to call distanceTo(Point p) of Point.java into Point2.java under a method takes no parameter? There should be a way but I cannot find from my materials. Could anybody help me? It has been doing 2 days. Please help...</p> <p><strong>---------------------Point.java---------------------------------</strong></p> <pre><code>public class Point{ private int x; private int y; //x and y coordinates as parameters public Point(int x, int y){ this.x = x; this.y = y; } //I want to call this method by calling a method which taken no parameter in Point2.java. public double distanceTo(Point p){ return Math.sqrt(((x - p.x) * (x - p.x)) + ((y - p.y) * (y - p.y))); } } </code></pre> <p><strong>---------------------ClonePoint.java---------------------------------</strong></p> <pre><code>public class ClonePoint{ private int a; private int b; //x and y coordinates as parameters public ClonePoint(int a, int b){ this.a = a; this.b = b; } //I failed with this way. Can anybody correct me? public double measureDistance(){//it should be takes no parameter. return distanceTo(ClonePoint p) } } </code></pre> <p><strong>----------------------PointDriver.java-----------------------------</strong></p> <pre><code>public class PointDriver { public static void main(String [] args) { Point2 nn = new Point2(11, 22); Point2 mm = new Point2(33, 44); System.out.println(nn.distanceTo(mm)); //I succeeded with this! System.out.println(nn.measureDistance(mm)); //But I got an error illegal start of expression } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
