JAVA Data Types - Part 1
0 likes1,494 views
Java is a statically-typed language that uses primitive data types like byte, short, int, long, float, double, char, and boolean as well as corresponding wrapper classes. The document demonstrates getting the maximum values of each primitive type in Java and displaying them.
![public class MaxDemo {
public static void main(String args[]) {
//integers
byte largestByte = Byte.MAX_VALUE;
short largestShort = Short.MAX_VALUE;
int largestInteger = Integer.MAX_VALUE;
long largestLong = Long.MAX_VALUE;
//real numbers
float largestFloat = Float.MAX_VALUE;
double largestDouble = Double.MAX_VALUE;
//other primitive types
char aChar = 'S';
boolean aBoolean = true;
}

JAVA Data Types - Part 1
- 1. Data Types in JAVA
- 2. Java is a Statically-Typed Language. Ex : variabletype variablename = data; Dynamically-Typed Languages include (Ruby,Tcl,Python,JavaScript) Primitive Types : Wrapper Types :
- 3. primitive type Wrapper type byte Byte short Short int Integer long Long float Float double Double char Character boolean Boolean
- 4. public class MaxDemo { public static void main(String args[]) { //integers byte largestByte = Byte.MAX_VALUE; short largestShort = Short.MAX_VALUE; int largestInteger = Integer.MAX_VALUE; long largestLong = Long.MAX_VALUE; //real numbers float largestFloat = Float.MAX_VALUE; double largestDouble = Double.MAX_VALUE; //other primitive types char aChar = 'S'; boolean aBoolean = true; } }
- 5. //Display them all. System.out.println("largest byte value is " + largestByte + "."); System.out.println("largest short value is " + largestShort + "."); System.out.println("largest integer value is " + largestInteger + "."); System.out.println("largest long value is " + largestLong + "."); System.out.println("largest float value is " + largestFloat + "."); System.out.println("largest double value is " + largestDouble + "."); The largest byte value is 127. The largest short value is 32767. The largest integer value is 2147483647. The largest long value is 9223372036854775807. The largest float value is 3.4028235E38. The largest double value is 1.7976931348623157E308.
