| Data Type | Default Value (for fields) |
|---|---|
| byte | 0 |
| short | 0 |
| int | 0 |
| long | 0L |
| float | 0.0f |
| double | 0.0d |
| char | ‘u0000’ |
| String (or any object) | null |
| boolean | false |
Live Example : Default value of Data Type
Sample Program that will illustrate Default Value Stored in Each Primitive Data Type Variable
public class DefaultValue {
static boolean bool;
static byte by;
static char ch;
static double d;
static float f;
static int i;
static long l;
static short sh;
static String str;
public static void main(String[] args) {
System.out.println("Bool :" + bool);
System.out.println("Byte :" + by);
System.out.println("Character:" + ch);
System.out.println("Double :" + d);
System.out.println("Float :" + f);
System.out.println("Integer :" + i);
System.out.println("Long :" + l);
System.out.println("Short :" + sh);
System.out.println("String :" + str);
}
}Output :
Bool :false Byte :0 Character: Double :0.0 Float :0.0 Integer :0 Long :0 Short :0 String :null
