java - 有没有办法在Java中满足某个条件时结束递归方法？

Question

有没有办法在满足条件时突然返回调用下面方法的方法？类似于 break for 循环。

public void createTree(TreeNode tree) throws IOException {
    if (i >= preorder.length) {
        // Leave recursive method
    } else if (preorder[i] == '0') {
        tree.value = '0';
        tree.left = tree.right = null;
        i++;                
    } else {
        tree.value = preorder[i];
        i++;
        tree.left = new TreeNode();
        createTree(tree.left);
        tree.right = new TreeNode();
        createTree(tree.right);
    }
}

谢谢。

您可以简单地让方法返回。然后向后递归，执行剩下的语句。
