Java Integer toUnsignedLong() Method

The toUnsignedLong() is a Java Integer class method which converts the argument to a long by an unsigned conversion. In an unsigned conversion to a long, the high-order 32 bits of the long are zero and the low-order 32 bits are equal to the bits of the integer argument.

Syntax:

Following is the declaration of toUnsignedLong() method:

Parameter:

DataType	Parameter	Description	Required/Optional
int	i	It is a value which is used to convert to an unsigned long.	Required

Returns:

The toUnsignedLong() method returns the argument converted to long by an unsigned conversion.

Exceptions:

Compatibility Version:

Java 1.8 and above

Example 1

  public class IntegerToUnsignedLongExample1 {  public static void main(String[] args) {      int x1 = -5;      int x2 = 5;      int y1 = -6;      int y2 = 6;      //Performs unsigned operation treating x and y holding unsigned values      long ux1 = Integer.toUnsignedLong(x1);      long ux2 = Integer.toUnsignedLong(x2);      long uy1 = Integer.toUnsignedLong(y1);       long uy2 = Integer.toUnsignedLong(y2);          System.out.println(“Unsigned x1  = ” + ux1);      System.out.println(“Unsigned x2  = ” + ux2);      System.out.println(“Unsigned y1  = ” + uy1);          System.out.println(“Unsigned y2  = ” + uy2);            }  }  

Test it Now

Output:

Unsigned x1  = 4294967291  Unsigned x2  = 5  Unsigned y1  = 4294967290  Unsigned y2  = 6

Example 2

  import java.util.Scanner;  public class IntegerToUnsignedLongExample2 {  public static void main(String[] args) {  //Enter user input  System.out.print(“Enter a value to perform unsigned operation: “);  Scanner s = new Scanner(System.in);  Integer value = s.nextInt();  //Get the toUnsignedLong() method result  Long result = Integer.toUnsignedLong(value);  // print the result  System.out.println(“Output: “+result);  s.close();              }  }  

Output:

Enter a value to perform unsigned operation: 32435  Output: 32435

Example 3

  import java.util.Scanner;  public class IntegerToUnsignedLongExample3 {  public static void main(String[] args) {  //Enter user input  System.out.print(“Input value to perform unsigned operation: “);  Scanner s = new Scanner(System.in);  Integer value = s.nextInt();  //Print the result  System.out.println(“Output: “+Integer.toUnsignedLong(value));  s.close();              }  }  

Output:

Input value to perform unsigned operation: -GSDJD  Exception in thread "main" java.util.InputMismatchException  at java.base/java.util.Scanner.throwFor(Scanner.java:939)  at java.base/java.util.Scanner.next(Scanner.java:1594)  at java.base/java.util.Scanner.nextInt(Scanner.java:2258)  at java.base/java.util.Scanner.nextInt(Scanner.java:2212)  at myPackage.IntegerToUnsignedLongExample3.main(IntegerToUnsignedLongExample3.java:8)
