怎么獲取私有的方法
private?void???ceshi(int?a){
????System.out.println("0000000000");
}????ceshi?a=new?ceshi();
Class?c=a.getClass();
????try?{
????????Method?m=c.getMethod("ceshi",int.class);
????????m.invoke(a,1);
????}catch?(Exception?e){
????????e.printStackTrace();
????}

首先你要明白它的訪問權(quán)限，了解后，根據(jù)相應(yīng)權(quán)限用get方法就行

我已經(jīng)通過度娘知道答案了。可以獲取

我也想問，應(yīng)該是不行的吧，如果可以用反射獲得private方法太不安全了，那public和private一點(diǎn)區(qū)別也沒了
