在java中显示特定行JTable

Question

我有一个Java表和TableModel.each row(element)有一个ID。我想显示特定的ID。如何过滤这些元素？选定的ID可以更改。

例如：

public class L { 
int id; 
String name; 
String family; 
} 

//---- 

private static final String[] columnNames = { "name","family"}; 
private static final Class[] columnClasses = {class.String.class,String.Class}; 
private Vector<L> list = Vector<L>(); 

list.add(new L(1,"A","b")); 
. 
. 
. 
list.add(new L(100,"AB","aa"); 

我想显示与此ID的元件，例如{1 39 45 55 22}。

如何筛选这些ID？

Answer 1

你可以用的RowFilter和TableRowSorter还做到这一点：

final int[] ids = new int[]{1, 39, 45, 55, 22}; 
RowFilter<Object, Object> filter = new RowFilter<Object, Object>() { 
    public boolean include(Entry entry) { 
    L currentObject = (L) (entry.getValue(0)); 
    for(int i=0;i<ids.length;i++){ 
     if(currentObject.getId()==ids[i]){ 
      return true; 
     } 
    } 
    return false; 
    } 
}; 

TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(model); 
sorter.setRowFilter(filter); 
yourTable.setRowSorter(sorter); 

测试，它为我工作
