可以通過流的形式讀取到所有內(nèi)容，之后在轉(zhuǎn)換成元素的形式進(jìn)行實現(xiàn)。舉例：

importjava.io.BufferedReader;

importjava.io.FileReader;

importjava.util.*;

publicclassTest{

publicstaticvoidmain(String[]args){

Hashtable<String,String[]>dict=newHashtable<String,String[]>();

try{

BufferedReaderreader=newBufferedReader(newFileReader("test.csv"));

Stringline=null;

while((line=reader.readLine())!=null){

Stringitem[]=line.split(",");

Stringitem2[]=newString[19];

System.arraycopy(item,1,item2,0,19);

dict.put(item[0],item2);

}

Enumeratione2=dict.keys();

while(e2.hasMoreElements()){

Stringkey=(String)e2.nextElement();

System.out.println(key);

String[]dd=(String[])dict.get(key);

for(inti=0;i<dd.length;i++){

System.out.print(dd[i]+"\t");

}

System.out.println();

}

}

catch(Exceptione){

e.printStackTrace();

}

}

}
