In java we have garbage collector , which is call by JVM in equal interval of time and remove garbage values or variables.

Answer / mihirdash

first take an example of c/c++,here the decaration and initialization is the programmer responsibility if not it gives the garbage value.but in java every thing is taken by jvm.we can declare any number of variable but it should be initialized.otherwise if we are going to use the uninitialized varibles the java compiler gives error.so there is no garbage value in java.
and if youu are created a object the keyword new is assigned default value during crreation of object

Answer / mihirdash

Because in java all declare variables are known to programmer.other wise it create some logical error.let us take an example of c++/c language if declare 100 variable it is so difficult to remember which will i initialise and it will effect my output result .so,that there is no garbage values
in java.

Answer / mamitha
