[Problem log] Java about mutable parameter overloading problems

Suddenly found that Java variable parameter overload is ambiguous, but do not know how to handle the internal Java, specifically to do the following experiments:

The test code is as follows:

1 /**2 * Created by Ieayoio on 16-3-1.3  */4  Public classVartest {5 6      Public Static voidaaaint... a) {7SYSTEM.OUT.PRINTLN ("Variable parameter overloading");8     }9 Ten      Public Static voidaaainta) { OneSYSTEM.OUT.PRINTLN ("Non-volatile parameter overloading"); A     } -      Public Static voidMain (string[] args) { -          the     } -}

1. Add AAA () on line 14 and run the result as follows:

Variable parameter overloading

Process finished with exit code 0

2. Add AAA (111,111) on line 14 and run the result as follows:

Variable parameter overloading

Process finished with exit code 0

3. Add AAA (111) On line 14 and run the result as follows:

Non-volatile parameter overloading

Process finished with exit code 0

4. Change the code to the following:

1 /**2 * Created by Ieayoio on 16-3-1.3  */4  Public classVartest {5 6      Public Static voidaaainta) {7SYSTEM.OUT.PRINTLN ("Non-volatile parameter overloading");8     }9 Ten      Public Static voidaaaint... a) { OneSYSTEM.OUT.PRINTLN ("Variable parameter overloading"); A     } -  -      Public Static voidMain (string[] args) { theAAA (111); -     } -}

The result remains:

Non-volatile parameter overloading

Process finished with exit code 0

Conclusion: When using the variable-parameter overloading method, the non-mutable parameter method is preferred to execute the program within Java.
