public class Application {
public static void main(String[] args) {

String one = "Hello";
String two = "Hello";

if(one == two) {
System.out.println("one == two";
}
else {
System.out.println("one != two";
}
}
}

interface IFruit
{
public String TYPE = "Apple";
}

class Fruit implements IFruit
{

}

public class Application {
public static void main(String[] args) {
System.out.println(Fruit.TYPE);
}
}

what does the following code print out and why

public class Test { public static void main(String[] args) { System.out.println(Math.min(Double.MIN_VALUE, 0.0d)); } }

public int compareTo(Object o){ Employee emp = (Employee) emp; return this.id - o.id; }

int x = 0;
boolean bExit = false;

Thread 1 (not synchronized)
x = 1;
bExit = true;

Thread 2 (not synchronized)
if (bExit == true)
System.out.println("x=" + x);

makavele:
solve these
when u are thru, i will post another

What does the following code print out?





Does the following code compile or not?

Futureviz:

k
the answer should be one==two
because the both string hold the same string word.
and to the other question the code wouldn't compile
.type is not a method
it is a field in the interface iFruit.

What is the issue with following implementation of compareTo() method




Consider the following Java code snippet, which is initializing two variables and both are not volatile, and two threads T1 and T2 are modifying these values as following, both are not synchronized



Now tell us, is it possible for Thread 2 to print “x=0”?

Futureviz:


sir!!! men am lost. am still a beginner. i just read java7 for absolute beginner.....sir i want to become like u. pls advice me am far

now that i know java , should i jump into android development..

lol, in ur own words, you said



these questions are practice interview questions and i never knew their answers too . . NOT UNTIL, i forced myself to learn them by hook or crook . . .

truth is, we never stop learning, the only ppl who know it all, are the producers (writers) of the programs, the real owners
but for we end-users, we keep learning . . . i used to love java ( i remmber wen i wrote a typical ATM program, and felt like a guru, but i fell out of love with it . . i am more of a PHP person now )

if u have fast internet i can send u alink to download a very intensive java video tutorial . . its about 3GB in size . . .
lock yourself indoors and code till you get sick and tired of coding . .
