    <p>i was asked a few java interview questions which i had no idea how solve could use some answers</p> <ol> <li><p>write a method which takes an int so the method would be </p> <p>public void somemethd(int i){}</p> <p>Now if i=1 then it should print true and if i=2 it should print false but you cannot use any conditional operators nor can you use if or switch</p></li> <li><p>how do two threads pass data in between each other, like let lets say you start 2 threads and you want to make one thread make the other thread wait. he rephrased the question to make it simpler, what if i have a varible in 1 thread and i want to send it to another thread how to do that.</p></li> <li><p>what if there is a non static method in base class and you make it a static method in derived class, would you get the same error as if u has a static method in base and u try to make it non static in derived class</p></li> <li><p>what is the use of overloading other than same name for different method? (i guess i should have said constructor overloading but it just didnt come to me, is there anything else)</p></li> <li><p>the syntax is not correct but u can jus assume everything is fine </p> <p><pre><code></p> <p>class base{</p> <p>show(){</p> <p>this.mymethod(); }</p> <p>mymethod(){ /... } }</p> <p>class derived extends base{</p> <pre><code>show(){ super.mymethod(); } mymethod(){ /... } } </code></pre></li> </ol> <p>now what happens when i do the following</p> <p>a. </p> <pre><code>base b = new derived(); b.show(); </code></pre> <p>b. </p> <pre><code>derived d= new base(); d.show(); </code></pre> <p>c. what if there was no show method in base n i did</p> <pre><code> base b = new derived(); b.show(); </code></pre> <p>d. what if there was no show method in base n i did</p> derived d= new base(); d.show(); </code></pre>

    1. COI only got as far as the first question - which is totally nonsensical. I hope your interviewer explained it really rather more clearly.

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.
