== Java Short Example ==



<source lang="java">

public class Main {
public static void main(String[] args) {
short s = 10;
Short sObj1 = new Short(s);
Short sObj2 = new Short("10");
System.out.println(sObj1);

== Java short: short is 16 bit signed type ranges from �32,768 to 32,767. ==



<source lang="java">

public class Main {
public static void main(String[] args) {
short s1 = 50;
short s2 = 42;
System.out.println("Value of short variable b1 is :" + s1);
System.out.println("Value of short variable b1 is :" + s2);
}
}
/*
Value of short variable b1 is :50
Value of short variable b1 is :42
*/

</source>



== Java Sort short Array ==



<source lang="java">

import java.util.Arrays;
public class Main {
public static void main(String[] args) {
short[] s1 = new short[] { 31, 21, 51, 41, 11 };
for (short s : s1) {
System.out.print(" " + s);
}
Arrays.sort(s1);
for (short s : s1) {

Arrays.sort(s2, 1, 4);
for (short s : s2) {
System.out.print(" " + s);
}
}
}

</source>



== Short class creates primitives that wrap themselves around data items of the short data type ==



<source lang="java">

public class MainClass {
public static void main(String[] args) {
short s = -1800;
Short s2 = new Short(s);
System.out.println(s2.shortValue());
}
}

</source>



== Shorts Vs Ints ==



<source lang="java">

public class ShortsVsInts {
public static void main(String[] unused) {
short i,j;
i = 30;
j = ++i; // works
j += 1; // works
j += 32768; // compiles; truncates at run time!
System.out.println(j);
System.out.println(Short.MAX_VALUE);
//j = j + 1; // won"t compile
}
}

</source>



== short value ==



<source lang="java">

public class Variables {
public static void main(String[] arguments) {
final char UP = "U";
byte initialLevel = 12;
short location = 13250;
int score = 3500100;
boolean newGame = true;
System.out.println("Level: " + initialLevel);
System.out.println("Up: " + UP);
}
}

</source>



== Use Short constructor to convert short primitive type to Short object ==



<source lang="java">

public class Main {
public static void main(String[] args) {
short s = 10;
Short sObj = new Short(s);
System.out.println(sObj);
}
}

</source>



== Use toString method of Short class to convert Short into String. ==



<source lang="java">

public class Main {
public static void main(String[] args) {
short s = 10;
Short sObj = new Short(s);
String str = sObj.toString();
System.out.println(str);
}
}
