工作要求，要將儲存在原物件中的值部分轉存到另一物件，沒有利用反射前的程式碼為：

public NewLCContTable replace(LCContTable mLcContTable){
		NewLCContTable newlc=new NewLCContTable();
		newlc.setAgentCode(mLcContTable.getAgentCode());
		newlc.setAgentCom(mLcContTable.getAgentCom());
		newlc.setCInValiDate(mLcContTable.getCInValiDate());
		newlc.setCInValiTime(mLcContTable.getCInValiTime());
		newlc.setContNo(mLcContTable.getContNo());
		newlc.setCValiDate(mLcContTable.getCInValiDate());
		newlc.setCValiTime(mLcContTable.getCInValiTime());
		newlc.setManageCom(mLcContTable.getManageCom());
		newlc.setPayIntv(mLcContTable.getPayIntv());
		newlc.setPayMode(mLcContTable.getPayMode());
		newlc.setPolApplyDate(mLcContTable.getPolApplyDate());
		newlc.setPrtNo(mLcContTable.getPrtNo());
		newlc.setSaleChnl(mLcContTable.getSaleChnl());
		
		
		
		return newlc;
		
	}
 

public class Clone {
	public static void main(String[] args) {
		
		LCContSchema lcContSchema=new LCContSchema();
		lcContSchema.setPrtNo("00000");
		lcContSchema.setContNo("123456");
		LCPolSchema lcPolSchema=new LCPolSchema();
		lcPolSchema.setOperator("123");
		clone(lcContSchema, lcPolSchema);		
		System.out.println(lcPolSchema.getPrtNo());
		System.out.println(lcPolSchema.getContNo());
		System.out.println(lcPolSchema.getOperator());
		System.out.println(lcContSchema.getOperator());
		System.out.println(lcPolSchema);
	}
	public static Object clone(Object old,Object news){
		Object o1=news;
		Method [] m1=news.getClass().getMethods();
		for(Method m:m1){
			String methodname=m.getName();
			
			if(methodname.indexOf("set")!=-1){
				String name=methodname.replaceAll("set", "get");
				Method m2=null;
				try {
					m2=old.getClass().getMethod(name, null);
				} catch (SecurityException e) {					
					e.printStackTrace();
				} catch (NoSuchMethodException e) {

				System.out.println(m.getName());

	}
}

開了下api修改了下程式碼
