hey guys really sorry in the for loop i=0 and not i-0

The way u explained is excellent suchitra...
Thax a lot

This is from K&B chapter 1 language fundamentals...Please let me know about the logic here...
public class test
{
public static void main(String []args)
{
int [][][] x = new int[3][][];
int i,j;
x[0] = new int[4][];
x[1] = new int[2][];
x[2] = new int[5][];
for(i- 0;i<x.length;i++)
for(j=0;j<x[i].length;j++)
{
x[i][j] = new int[i+j+1];
System.out.println("size ="+x[i][j].length);
}
}
}


Answer of this is:11

thanks

thanx charles...i figured out others too...

thanks for ur explanation...i wont go wrong in future...

thanx john...

I would like to know concept behined this one....
public class example {
int i[] = {0};
public static void main(String args[]) {
int i[] = {1};
change_i(i);
System.out.println(i[0]);
}
public static void change_i(int i[]) {
int j[] = {2};
i = j;
}
}


The program does not compile.
The program prints 0.
The program prints 1.
The program prints 2.
The program prints 4.

answer is rogram prints 1

one more question

public class example {
int i = 0;
public static void main(String args[]) {
int i = 1;
change_i(i);
System.out.println(i);
}
public static void change_i(int i) {
i = 2;
i *= 2;
}
}

answer is rogram prints 4

let me know about the logic please

thanks in advance

please let me know how it works...
public class test {
public static void main(String args[]) {
System.out.println(args[0]+" "+args.length);
}
}


1.java
2.test
3.lets
4.3
5.4
6.5
7.6

output is :3 option and and fifth(ie lets and 4)

let me know
thanks

Anyone please let me know the output of both...
executed by entering "java test lets see what happens".
1.public class test {
public static void main(String args[]) {
System.out.println(args[0]+" "+args[args.length-1]);
}
}

Answer for this is:lets happens

2.
public class test {
public static void main(String args[]) {
System.out.println(args[0]+" "+args[args.length]);
}
}


answer is:The program will throw an ArrayIndexOutOfBounds exception
