Examples of java.util.Stack.push()

java.util.Stack.push()
Pushes an item onto the top of this stack. This has exactly the same effect as:
```
 addElement(item)
```
@param item the item to be pushed onto this stack. @return the item argument. @see java.util.Vector#addElement

        TreeDrawerNode node = (TreeDrawerNode) remaining.pop();
        if (node.getCorr() < curCorr)

        TreeDrawerNode leftNode = node.getLeft();
        if (leftNode != null) remaining.push(leftNode);


        TreeDrawerNode rightNode = node.getRight();
        if (rightNode != null) remaining.push(rightNode);
      }
      return curCorr;
