Java String

Tostring() method is implemented by all java objects that will be returning String object, which will be describing that object in a best manner. For instance, red colored object can be printed out by using:

Java Code:

Color color = new Color( 255, 0, 0 );
String colorStr = color.toString();
Console.println( colorStr );

Printout will be:

Java Code:

java.awt.Color[r=255,g=0,b=0]

In such a case, there is no need to call tostring() method explicitly. A version is present in the printIn() method in which an object is taken as an argument. This version calls tostring() method implicitly for the print result.

When a string object is concatenated with other object type, conversion to String happens implicitly. For instance, type:

Java Code:

Color color = new Color( 255, 0, 0 );
String str = "My color looks like: " + color;
Console.println( str );

Following will be obtained, on the console:

My color looks like: java.awt.Color[r=255,g=0,b=0]
