Answer 1

应该这样做。

public boolean existsInTable(JTable table, Object[] entry) {

    // Get row and column count
    int rowCount = table.getRowCount();
    int colCount = table.getColumnCount();

    // Get Current Table Entry
    String curEntry = "";
    for (Object o : entry) {
        String e = o.toString();
        curEntry = curEntry + " " + e;
    }

    // Check against all entries
    for (int i = 0; i < rowCount; i++) {
        String rowEntry = "";
        for (int j = 0; j < colCount; j++)
            rowEntry = rowEntry + " " + table.getValueAt(i, j).toString();
        if (rowEntry.equalsIgnoreCase(curEntry)) {
            return true;
        }
    }
    return false;
}
