[SOLVED] Why import isnt needed whn ref is used without storing to local variable

[N_i_X]

Hello, Guys
This is my first thread to the Forum....

Consider this statement

System.getProperties().getProperty("propertyname") ;

for this statement import of java.util.Properties is not required, but we are using method of Properties

but it will required for this statements.
Properties props = System.getProperties();
props.getProperty("propertyname");

Whats the reason??

Regards,

System.getProperties().getProperty("propertyname") ;

The System class does import java.util.Properties so it can handle this internally and return the String.
If you want to declare a Properties type/object in your app then you must import java.util.Properties into your app to support the type.
