Data Types Default Values Java

Java does not support garbage values. An unassigned local variable gives compilation error and an instance (global) variable takes a default value. Following program illustrates the default values given by JVM for unassigned instance variables.

String is not a data type. If not assigned, String takes null as the default.

Observe the screenshot on Data Types Default Values Java. The default values for whole numbers is 0, for floating-point numbers is 0.0 and for primitive data type boolean it is false. String takes null and char does not print any value. Actually, it prints a value equivalent to Unicode value of /u0000 which prints nothing.
