Return an integer value as byte, double, float, int, long and short
byte byteValue()
- Returns the value of this Integer as a byte.
double doubleValue()
- Returns the value of this Integer as a double.
float floatValue()
- Returns the value of this Integer as a float.
int intValue()
- Returns the value of this Integer as an int.
long longValue()
- Returns the value of this Integer as a long.
short shortValue()
- Returns the value of this Integer as a short.
public class Main {
public static void main(String[] args) {
Integer integerObject = new Integer("1234567");
byte b = integerObject.byteValue();
System.out.println("byte:"+b);
short s = integerObject.shortValue();
System.out.println("short:"+s);
int i = integerObject.intValue();
System.out.println("int:"+i);
float f = integerObject.floatValue();
System.out.println("float"+f);
double d = integerObject.doubleValue();
System.out.println("double:"+d);
long l = integerObject.longValue();
System.out.println("long:"+l);
}
}
The output:
byte:-121
short:-10617
int:1234567
float1234567.0
double:1234567.0
long:1234567
