报错：efore: salary=50000.0
Exception in thread "main" java.lang.NoSuchMethodError: Employee.raiseSalary(D)V
at ParamTest.tripleSalary(ParamTest.java:32)
at ParamTest.main(ParamTest.java:14)
请问这个是什么问题？

[wq00168]

不会啊，我用eclipse运行就是有错的，还是报：Testing tripleValue
Before: percent=10.0
End fo method: x=30.0
After: percent=10.0

Testing tripleSalary:
Before: salary=50000.0
Exception in thread "main" java.lang.NoSuchMethodError: Employee.raiseSalary(D)V
at ParamTest.tripleSalary(ParamTest.java:32)
at ParamTest.main(ParamTest.java:14)
为什么会是这样啊？

[wq00168]

在classic Employee 报错，出现已定义类型 Employee，这个是什么意思？

[弘石]

eclipse里运行过，没有错误

[wq00168]

不会吧，我这个怎么报错了

[lovecj6185]

既然大家运行都没有错
说明程序本身没有问题

那是不是楼主同一个包中有类发生冲突阿
方法的命名什莫德

[wq00168]

我再看看

[say___baby]

没有错误啊，楼主的JDK是好多版本的哦

[caironghuicxz]

格式调调，这样会让人很累的

[YY_MM_DD]

x.raiseSalary(200);
把他改个double型
x.raiseSalary(Double.valueOf(200));

[beijixing022]

将200改为200d试试~~~

[bigbug9002]

静态方法中不能调用非静态的方法。

[bigbug9002]

不对,看错了。
1,2的是对的。

[YY_MM_DD]

No error!啊 ...我晕...

Testing tripleValue
Before: percent=10.0
End fo method: x=30.0
After: percent=10.0

Testing tripleSalary:
Before: salary=50000.0
End of method: salary =150000.0
After: salary=150000.0

Testing swap:
Before: a = Alice  b = Bob
End of method: x=Bob  y=Alice
After: a = Alice  b = Bob

[lovecj6185]

确实运行楼主的代码没有报错
结果和楼上是一样的

是否没有得出楼主想要得结果呢
