Getting Java variable Names & Values in functions() [duplicate]

This question already has an answer here:

• Can I get information about the local variables using Java reflection? 5 answers

Is there a way to get the Names & Values of Java declared-variables in a java function() ?

I know how to get global class variables through Reflection using the following code.

Field[] fields = this.getClass().getDeclaredFields();
for(Field field: fields)
{
 System.out.println("Name="+ field.getName()+"/Value="+ field.toString()+" / "+field.get(this));
}

But how do I get to the Locally declared variables in a function()?

My objective is to log all variables to logfile upon exception

try{}catch(Exception e){/*code goes here*/}
