Java 将表上的数据显示到jfreechart中

我正在构建一个应用程序来检查两个或更多java代码之间的相似性。现在，我有一个数据，我正在存储到一个表中。构建此表的代码如下所示

public final class ASTParseUnit {

String IDLexer;

public ASTParseUnit(final IParserSelector parserSelector) {
    this.parserSelector = parserSelector;
}

public String getIDLexer() {
    return IDLexer;
}

public void setIDLexer(String iDLexer) {
    IDLexer = iDLexer;
}

public ASTManager parse(final JCCDFile[] files) {

    final ASTManager container = new ASTManager(
            TipeNode.PROJECT.getTipe(), null);


    JCCDFile temp;
    temp = files[0];
    String name = temp.getName(); 
    String idLexerSeleksi = "";

    StringBuilder nameOfFileMainFile = new StringBuilder();

    StringBuilder countLevenstheins = new StringBuilder();
    StringBuilder countJaccards = new StringBuilder();
    StringBuilder countCosines = new StringBuilder();


    for (final JCCDFile file : files) {
        container.tandaiNodeRoot(); 

        parseTree(file, container);
        if (name.equals(file.getName())) {
            idLexerSeleksi = getIDLexer();
        }

        LevenshteinDistance lv = new LevenshteinDistance();
        SimilarityRunner sr = new SimilarityRunner(); // my class to count similiarity

        if (idLexerSeleksi != getIDLexer()) {

            nameOfFileMainFile.append(file.getName()); 
            System.out.println(temp.getName() + " ==> " + file.getName());



            countLevenstheins.append(lv.printDistance(idLexerSeleksi, getIDLexer()));
            countJaccards.append(sr.hitungJaccard(idLexerSeleksi, getIDLexer()));
            countCosines.append(sr.hitungCosine(idLexerSeleksi, getIDLexer()));

        }
    }

    String enemy = nameOfMainFile.toString();
    String resultOfLevenstheins = countLevenstheins.toString();
    String resultOfJaccards = countJaccards.toString();
    String resultOfCosines = countCosines.toString();

    DefaultTableModel model = (DefaultTableModel) Main_Menu.jTable3.getModel();
    List<Report3> theListData = new ArrayList<Report3>();
    Report3 persentaseTabel = new Report3();

    persentaseTabel.setMainFile(name);
    persentaseTabel.setComparingFile(enemy);
    persentaseTabel.setLevenstheins(resultOfLevenstheins);
    persentaseTabel.setJaccard(resultOfJaccards);
    persentaseTabel.setCosine(resultOfCosines);

    theListData.add(persentaseTabel);
    for (Report3 report3 : theListData) {
        model.addRow(new Object[]{
            report3.getMainFile(),
            report3.getComparingFile(),
            report3.getLevenstheins(),
            report3.getJaccard(),
            report3.getCosine(),});
    }

    return container;
}

这是我的应用程序的屏幕截图

假设您希望图表反映（可能正在更改）表格条目，请在您的

表格模型

中添加一个。根据收到的

TableModelEvent

，相应地更新

CategoryDataset

；听力图表将自我更新以作出响应

如果在评估查询和比较函数后表模型没有改变，请使用前面提到的

jdbcategorydataset

查询数据库；然后构建相应的表格模型。

另请参见。
