Thread: Having some nested loop problem

Hmm , the assignment require me to display number in this pattern

pattern 1

123456
12345
1234
123
12
1

pattern 2
123456
..12345
...1234
.....123
.......12
........1 (Replace dot with spacebar because it will become like pattern 1 if i simply put spacebar infront of the number


and the result of my coding shows only pattern 1 , pattern 2 is blank / skipped

i could get the result i want using same calculation in system.out.print
but the assignment require us to use joptionpane with countinue label nested for loop, so i dont know which part of my above code is wrong and made the result for pattern 2 is not displaying

 (int row = 6; row >= 1; row-- ){
for ( int column = 1; column <= row; column++ )
System.out.print(column + "" );
System.out.println();
}
System.out.println();
System.out.println();
 
 
 
for (int row = 6; row >= 1; row-- ){
for (int space = 6; space > row; space-- )
System.out.print( " " );
for (int column = 1; column <= row; column++ )
System.out.print( column + "" );
System.out.println();

hmm , this part is not showing in joptionpane output dialog

  nextnextRow:  
         for ( int row = 6; row >= 1; row-- ) {
            output += "\n";
 
         for (int space = 6; space > row; space-- ) {
 
            output += "\t";
            for (int column = 1; column <= row; column++ ) {
 
               if (column > space)
                  continue nextnextRow; 
               output += column ;
            }
         }
 
      JOptionPane.showMessageDialog(
         null, output,"Result",
         JOptionPane.INFORMATION_MESSAGE );
      System.exit( 0 );
   }
}

blank , it just show pattern I and skipped pattern II

hmm, i did some correction on the code , now it showing Pattern 1..while the calculation is for pattern 2 , i think it skipped " for (int space = 6; space>=row; space-- ) { output += "\t" ; "
this part?

 { nextnextRow:
 
         for ( int row = 6; row >= 1; row-- ) {
            output += "\n";
 
              for (int space = 6; space>=row; space-- ) {
 
                 output += "\t" ;
 
            for (int column = 1; column <= 10; column++ ) {
 
                  if ( column > row )
                  continue nextnextRow; 
 
                      output += column ;

i don't think it has skipped that statement.
It enters the tabbed space("\t") after every newline character("\n") because of the '>=' in the condition space >= row.

You could change the condition for that loop to this -> [for(int space = 0; space < 6-row; space++) ].

That should do it, i suppose, I haven't tried running it though.

Also, the loop containing variable column should NOT be a second-level nest.
It has to be nested only in the loop containing variable row.
And also there's no need for the label nextnextRow. Just a plain continue statement is enough.(makes the code simpler)

Just these changes(one about the condition that i mentioned, other about the nesting and last one about the label), and its done!

There's one more thing, the dialog boxes don't seem to include the tabbed spaces("\t") in the ouput.
So, changing the statement from [output += "\t";] to [output += " ";] (that include two spaces) displays the second pattern as it should.

u can use float
