Consider this example, here we are declaring some of the variables with initial (default) values to them and then we will print the values. publicclassMain{publicstaticvoidmain(String[]args){inta=10;charb='X';floatc=10.235f;String str="Hello";System.out.println("a= "+a);System.out.pr...

In Java, the class designer can guarantee initialization of every object by providing a constructor. Note that the coding style of making the first letter of all methods lowercase does not apply to constructors, since the name of the constructor must match the name of the class exactly. A co...

char'u0000' booleanfalse String (or any object)null Noted that this is not the case withlocal variableorblock variable! In Java, if you have declared such variable without assiging value to it, it won't get assigned a default value like field variable. In fact, the compiler will throw...
char c = (char)('B'-1); //It also gives the result as 'A' only Here variable a,b & c represent the same values. In case of variable c cast is necessary because java performs all non-fraction arithmetic using four byte integers. The cast transforms it back to a two byte char ty...
4、This storage is wiped to zero, automatically setting all the primitives in thatDog object to their default values(zero for number and the equivalent forboolean and char)and the references to null. 5、Any initializations that occur at the point of field definition are executed. ...
