Java Initializer Program for initializing primitives, String, and Object
Initializer program
The Initializer program illustrates the use of automatic initialization.
It declares field variables of every primitive type, the String type, and object types.
It also declares a local array and then displays the values of these variables.
The Initializer program
class Initializer {
boolean bo;
byte by;
char c;
short s;
int i;
long l;
float f;
double d;
String str;
Object obj;
void run() {
short[] sh = new short[2];
System.out.println("boolean: "+bo);
System.out.println("byte: "+by);
System.out.println("char: "+c);
System.out.println("short: "+s);
System.out.println("int: "+i);
System.out.println("long: "+l);
System.out.println("float: "+f);
System.out.println("double: "+d);
System.out.println("String: "+str);
System.out.println("Object: "+obj);
System.out.println("sh[0]: "+sh[0]);
System.out.println("sh[1]: "+sh[1]);
}
public static void main(String[] args) {
Initializer app = new Initializer();
app.run();
}
}
Output of the above Java Program.

char:
short: 0
int: 0
long: 0
float: 0.0
double: 0.0
String: null
Object: null
sh[0]: 0
