class VariableNameClash
{
static int x=10;
This is a class variable with name x.
public static void main(String[] args)
{
int x=20;
This is a local variable with same name x;

System.out.println(x);
The local variable can be used directly

//System.out.println(this.x);
The static variable can be used using the this keyword if the method is not static type. If we remove static modifier of main we can use this type.

System.out.println(VariableNameClash.x);
Using the class name prefix we can directly use the static variable within the local context also.
}
}
