❶ java讀寫dbf文件

Java讀取DBF文件，需要載入開源jar包JavaDBF.jar，然後使用裡面的方法進行讀寫，示例如下：

packagesearch;
publicclassReadDBF{
publicstaticvoidmain(Stringargs[])

{
readDBF();
}
privatestaticvoidreadDBF()
{
try
{
System.out.println("正在讀取文件！");

DBFReaderdbfreader=newDBFReader("D:\ZG2011格式.dbf");
for(intb=0;b<dbfreader.getFieldCount();b++)
{
if(b>0)
{System.out.print(",");}
System.out.print(dbfreader.getField(b).getName().trim().toUpperCase());

if(b==(dbfreader.getFieldCount()-1))
System.out.print("
");
}
for(inti=0;dbfreader.hasNextRecord();i++)
{
String[]aobj=dbfreader.nextRecordString();
for(intb=0;b<dbfreader.getFieldCount();b++)
{
if(b>0)
System.out.print(",");
System.out.print(aobj[b].trim());

if(b==(dbfreader.getFieldCount()-1))
System.out.print("
");

}
}
System.out.println("讀取文件成功！");
}
catch(Exceptione)
{
	System.out.print(e.getMessage());
}
}

}

❷ java程序如何讀取dbf文件 最好寫上代碼

publicclassRwdbf{

publicstaticvoidreadDBF(Stringpath)

{

InputStreamfis=null;
try
{
//讀取文件的輸入流
fis=newFileInputStream(path);
//根據輸入流初始化一個DBFReader實例，用來讀取DBF文件信息
DBFReaderreader=newDBFReader(fis);
//調用DBFReader對實例方法得到path文件中欄位的個數
intfieldsCount=reader.getFieldCount();
System.out.println("欄位數:"+fieldsCount);
//取出欄位信息
for(inti=0;i<fieldsCount;i++)
{
DBFFieldfield=reader.getField(i);
System.out.println(field.getName());
}
Object[]rowValues;
//一條條取出path文件中記錄
while((rowValues=reader.nextRecord())!=null)
{
for(inti=0;i<rowValues.length;i++)
{
System.out.println(rowValues[i]);
}
}
}
catch(Exceptione)
{
e.printStackTrace();
}
finally
{
try{
fis.close();
}catch(Exceptione){}
}
}publicstaticvoidwriteDBF(Stringpath)
{

OutputStreamfos=null;
try
{
//定義DBF文件欄位
DBFField[]fields=newDBFField[3];
//分別定義各個欄位信息，setFieldName和setName作用相同，
//只是setFieldName已經不建議使用
fields[0]=newDBFField();
//fields[0].setFieldName("emp_code");
fields[0].setName("semp_code");
fields[0].setDataType(DBFField.FIELD_TYPE_C);
fields[0].setFieldLength(10);

fields[1]=newDBFField();
//fields[1].setFieldName("emp_name");
fields[1].setName("emp_name");
fields[1].setDataType(DBFField.FIELD_TYPE_C);
fields[1].setFieldLength(20);

fields[2]=newDBFField();
//fields[2].setFieldName("salary");
fields[2].setName("salary");
fields[2].setDataType(DBFField.FIELD_TYPE_N);
fields[2].setFieldLength(12);
fields[2].setDecimalCount(2);

//DBFWriterwriter=newDBFWriter(newFile(path));

//定義DBFWriter實例用來寫DBF文件
DBFWriterwriter=newDBFWriter();
//把欄位信息寫入DBFWriter實例，即定義表結構
writer.setFields(fields);
//一條條的寫入記錄
Object[]rowData=newObject[3];
rowData[0]="1000";
rowData[1]="John";
rowData[2]=newDouble(5000.00);

rowData[1]="Rohit";
rowData[2]=newDouble(7350.00);
writer.addRecord(rowData);

//定義輸出流，並關聯的一個文件
fos=newFileOutputStream(path);
//寫入數據
writer.write(fos);

//writer.write();
}catch(Exceptione)
{
e.printStackTrace();
}
finally
{
try{
fos.close();
}catch(Exceptione){}
}
}

publicstaticvoidmain(String[]args){
Stringpath="E:\tmp\2\xx.dbf";
try{
