Question

In Java, I want to go through a list of elements and insert a new one at the right place. I was thinking of doing it in this way:

for( Tab tab : tabList )
  if( newTab.getPriority() < tab.getPriority() ) {
    newTab.insertBefore(tab);
    break;
  }
if( tab == null )
  newTab.insertBefore(endMarker);

Unfortunately, tab is not accessible outside the for loop. Is there any simple way to do what I want or do I have to use a boolean?

Answer 1

It is better practice to use a tab variable outside the scope of the for loop

Tab selected_tab = null;

for ( Tab tab: tabList ) {
    if (tab_I_want(tab)) {
       selected_tab = tab;
       break;
    }
}

// selected_tab is either null or the tab you want
