printing 2-dimensional array 1

[technoknow]

public class MyArray
{
public static void main(String args[]) throws Exception
{
int i; int j;
String[][] friends =
{ {"Dave", "Henrich", "33"},
{"Jim", "Creighton", "42"},
{"Bob", "Wilson", "47"} };
for (i = 0; i< friends.length; i++)
for (j = 0; j < friends.length; j++)
System.out.println(friends[j]);
}
}

I'm trying to print this array with each row on 1 line like this:
Dave Henrich 33
Jim Creighton 42
Bob Wilson 47
But it comes out like this:
Dave
Henrich
33
Jim etc....
What am I doing wrong?
Thanks,

You are using println, so each time you print an item you print a new line.

for (i = 0; i< friends.length; i++)
{
  for (j = 0; j < friends[i].length; j++)
    System.out.print (friends[i][j] + &quot; &quot;);
  System.out.println ();
}

This code should work.

Globos,
Now all of the elements are printed on one line like this:
DaveHenrich33JimCreighton42, etc..
Any other ideas?
Thanks

hi

println : print & go next line
print : just print

so add new println statement after inner loop (don't forget { & } )

public class MyArray
{
public static void main(String args[]) throws Exception
{
int i; int j;
String[][] friends =
{ {&quot;Dave&quot;, &quot;Henrich&quot;, &quot;33&quot;},
{&quot;Jim&quot;, &quot;Creighton&quot;, &quot;42&quot;},
{&quot;Bob&quot;, &quot;Wilson&quot;, &quot;47&quot;} };
for (i = 0; i< friends.length; i++) {
for (j = 0; j < friends.length; j++){
System.out.print(friends[j]);
}
System.out.println();
}
}

Thanks fuadhamidov,
That's what I needed!

for (i = 0; i< friends.length; i++)
{
  for (j = 0; j < friends[i].length; j++)
    System.out.print (friends[i][j] + &quot; &quot;);
  System.out.println ();
}

tecknoknow, this code works fine on my PC, with Java 1.4.2_02 installed.

But the code from fuadhamidov doesn't work, when executed I get :

[Ljava.lang.String;@108786b[Ljava.lang.String;@119c082[Ljava.lang.String;@1add2dd
[Ljava.lang.String;@108786b[Ljava.lang.String;@119c082[Ljava.lang.String;@1add2dd
[Ljava.lang.String;@108786b[Ljava.lang.String;@119c082[Ljava.lang.String;@1add2dd

Moreover the inner for loop as a bad end condition
not

 for (j = 0; j < friends.length; j++)

but

 for (j = 0; j < friends[i].length; j++)

and the body of this loop doesn't seem to be correct too.

>>But the code from fuadhamidov doesn't work, when executed I get :

That's because fuadhamidov did not put his code between [ code ] and [ /code ] so that

friends[i].length

gets displayed by this forum as :
friends.length

[ i ] means &quot;display in italics&quot;
