need help with another loop

[nicky sajdok]

Hello again
The code below prints out this
[7,4,2,1,0]
addr1, id, phone, lastname, firstname
[9,8,6,5,3]
town, addr2, postcode, county, country

for (int ii2=0;ii2 < results2.size(); ii2++) {
  vv2 = (Vector)results2.elementAt(ii2);
   ste2 = vv2.toString();
  stb2 = new StringBuffer(ste2);
 stb12 = new StringBuffer();
 int is = stb2.length();
 int is2 = is-2;
 int is3 = is-1;
 stb2.replace(0,1,"");
 stb2.replace(is2,is3,"");
 for(int i222 = 0; i222 < vv2.size(); i222++){
 stb12.append(",");
 stb12.append("?");
 }
 stb12.replace(0,1,"");
 System.out.println(stb2);
     vv = (Vector)results.get(ii2);
     System.out.println(vv);
 }
 

my problem now is that i want to put another loop inside of it so that my code will print this
ben
[7,4,2,1,0]
addr1, id, phone, lastname, firstname
alex
[9,8,6,5,3]
town, addr2, postcode, county, country
this is my loop.

 
//names holds ben, alex.
for (i = 0; i < names.size(); i++){
  String name = (String)results1.get(i);
System.out.println(name);
}

thanks
nicky

You may have to do a triple loop, with {Ben, alex} at the outest, and manage to print the name just once.

and how would i do this?
thanks

i=0; i<2; i++
{
if (j + k) == 0
{
print( array[i] )
}
j=0; j<4; j++
{
k=0; k<4; k++
{
}
}
}

What I think Don was saying.

for( int i=0; i<2; i++)
{
  if (j + k) == 0
  {
    print( array[i] )
  }
  for( int j=0; j<4; j++)
  {
    for( int k=0; k<4; k++)
    {
      // Do something
    }
  }
}

If you need to understand how loops work I would suggest you start with a simpler demo example.

// single loop
int maxi = 3 ;
for( int i=0; i < maxi; i++)
{
  System.out.println("==> i: " + i) ;
}
// 2 nested loops
int maxi = 3 ;
int maxj = 2 ;
for( int i=0; i < maxi; i++)
{
  System.out.println("==> i: " + i) ;
  for{ int j=0; j < maxj; j++)
  {
    System.out.println(==> j: " + j) ;
  }
}

Start with these. Change the values, change what is printed, add code and see what happens...

Sorry for the bugs. I was in a hurry this morning.
To get this:
ben
[7,4,2,1,0]
addr1, id, phone, lastname, firstname
alex
[9,8,6,5,3]
town, addr2, postcode, county, country

:
for( int i=0; i<2; i++)
{       
     system.out.println( array_1[i] );     
     for( int j=0; j<4; j++)       
     {              
          for( int k=0; k<4; k++)
          {               
               if ( j == 0 )
               {
                    system.out.println( array_2[j+k] );                    
                    system.out.println( array_3[k] );               
                }          
           }     
     }
}

Not sure exactly what you are trying to show here, but the line

if ( j == 0 )

inside of this 'for'

for( int j=0; j<4; j++)   

doesn't make much sense to me.

[John Lee]

Here j==0 is extra. It looks like I can just print out the two statements.
