i used this code but didn't work.. can anyone help me... thanks in advance...
-
public ins_man(int b) {
initComponents();
int i,j;
for(i=1;i<b;i++)
{
jTextField[ i ].setVisible(false);
for(j=b+1;j<21;j++)
{
jTextField[ j ].setVisible(false);
}
}

I'm not sure what you're actually trying to accomplish. Your code does nothing but set the textfield's visibility to false, but it's looping over them multiple times. Are you trying to set the textfields from 0 to b to visible, and from b+1 to 21 to invisible? Or something like that? If you post code in the future, please wrap it in [code][/code] tags so it's more readable.
public ins_man(int b) {
initComponents();
int i,j;
for(i=1;i<b;i++)
{
jTextField[ i ].setVisible(false);
for(j=b+1;j<21;j++)
{
jTextField[ j ].setVisible(false);
}
}
}
