JTree - 如何使用For-Loop添加節點？

Question

我有一個簡單JTree，該系統增加了節點從相關瓦爾：

public void init() 
{ 
    final String section1 = "JAVA"; 

    final String section1_content1 = "Tutorial1"; 
    final String section1_content2 = "Tutorial2"; 
    final String section1_content3 = "Tutorial3"; 
    final String section1_content4 = "Tutorial4"; 
    final String section1_content5 = "Tutorial5"; 
    final String section1_content6 = "Tutorial6"; 

    final String content1a = "Introduction"; 
    final String content1b = "Hello World!"; 

    // Create the title node: 
    title = new DefaultMutableTreeNode(section1); 

    // Create and attach the 1st subtree: 
    selection = new DefaultMutableTreeNode(section1_content1); 

    selection.insert(new DefaultMutableTreeNode(content1a),0); 
    selection.insert(new DefaultMutableTreeNode(content1b),0); 

    title.insert(selection,0); 
} 

我想什麼，就是用一個for循環，避免額外selection.inserts

像

String[] sections = new String[]{ "Tutorial1", "Tutorial2", "Tutorial3", "Tutorial4", "Tutorial5", "Tutorial6" }; 

for (int i=0; i < sections.length; i++) { 
    selection = new DefaultMutableTreeNode(sections[i]); 
} 

我會怎麼做呢？

感謝

Answer 1

你可以把所有的值到一個枚舉並通過迭代來代替。

Answer 2

的解決方案很簡單：

for (int i=0; i<sections.length; i++) { 
    selection = new DefaultMutableTreeNode((sections[i])); 
    title.insert(selection,0); 
    } 

節[I]需要雙括號
