Java: should I use "this" keyword or "m_" prefix? [closed]

Question

To refer to instance variables, should I use the "this" keyword...

class Foo
{
    private int bar;

    public Foo(int bar)
    {
    this.bar = bar;
    }
}

OR the "m_" prefix (Hungarian naming convention where m means "member variable")...

class Foo
{
    private int m_bar;

    public Foo(int bar)
    {
    m_bar = bar;
    }
}

Are there any situations where one provides an advantage over the other?

Answer 1

this is standard, more readable, and less error prone.

It will help you when you are mistakenly shadowing variables or and trying to access non-static field in static code.

i.e to avoid this

int m_bar;
public Foo(int m_bar)
{
  m_bar = m_bar;
}

and static int m_bar;

int m_bar;
public Foo(int bar)
{
  this.bar = m_bar; // a warning static field being accessed as non-static
}
