    <p>I am wondering why i have to deal with two types of arguments;that of a constructor and that of a method.For instance i have this simple class that adds two numbers</p> <pre><code>class Calc{ private int x = 6; private int y; private char z = 'z'; public int getx(){ return x; } public char selfrecur(){ return this.z; } public int add(int one,int two){ return one + two; } public static void main(String[] args) { Calc gx = new Calc(); System.out.println(gx.x); System.out.println(gx.add(44,3)); System.out.println(gx.selfrecur()); } } </code></pre> <p>That works,and wow,wasn't that great.Now,i have this idea of having the constructor provide the arguments and the function's work will be to do the heavy computations.For instance in my class Kalc</p> <pre><code>class Kalc{ //** This example won't work ** private int x; private int y; private int z; public Kalc(int v1,int v2,int v3){ this.x = v1; this.y = v2; this.z = v3; } public int add(){ return newObject.x + newObject.y + newObject.z; //Gets the values of a new object and add them up } public int multiply(){ return newObject.x * newObject.y * newObject.z; //Gets the values of a new object and multiply them } public static void main(String[] args) { Kalc k = new Kalc(4,5,6); System.out.println(k.add()); System.out.println(k.multiply()); } } </code></pre> <p>I have been looking here <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html" rel="nofollow">http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html</a> for clues but so far nothing.Is this even possible?.</p> <p>Edit </p> <pre><code>class Kalc{ private int x; private int y; private int z; public Kalc(int v1,int v2,int v3){ this.x = v1; this.y = v2; this.z = v3; } public int add(){ return this.x + this.y + this.z; } public static void main(String[] args) { Kalc k = new Kalc(4,5,6); System.out.println(k.add); } } </code></pre> <p>Error</p> <pre><code>C:\ja&gt;javac Kalc.java Kalc.java:17: error: cannot find symbol System.out.println(k.add); ^ symbol: variable add location: variable k of type Kalc 1 error C:\ja&gt; </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.
