Java Integer compareUnsigned() Method

The compareUnsigned() is a method of Java Integer class which compares two integer objects numerically treating the values as unsigned. It returns the result of the value 0 if both arguments are equal; a value less than 0, if the first argument is less than the second argument; a value greater than 0 will be returned, if the first argument is less than the second argument. This method is specified by Comparable<Integer> Interface.

Note: This method cannot be compared to two different types of argument so, both the argument and the number should be the same type.

Syntax:

Following is the declaration of compareUnsigned() method:

Parameter:

DataType	Parameter	Description	Required/Optional
int	x	It is the first int value to be compared	Required
int	y	It is the second int value to be compared	Required

Returns:

The compareUnsigned(int x, int y) method will returns the following values:

0 = The value 0 if x=y,
-1 = The value less than 0 if x
1 = The value greater than 0 if x>y

Exceptions:

Compatibility Version:

Java 1.8 and above

Example 1

  public class IntegerCompareUnsignedExample1 {  public static void main(String[] args) {  int a = 55;  int b = 55;  int c = 110;  int d = 150;  int n = -8;   //output is zero, since a==b  System.out.println(“Output: “+Integer.compareUnsigned(a, b));  //output is less than zero, since a<c  System.out.println(“Output: “+Integer.compareUnsigned(a, c));  //output is greater than zero, since d>c  System.out.println(“Output: “+Integer.compareUnsigned(d, c));             //As 55 is greater than -8,but -8 will be treated as an unsigned number        //which will be greater than 55 Output will be a value less than zero  System.out.println(“Output: “+Integer.compareUnsigned(b, n));  }  }

Output:

Output: 0  Output: -1  Output: 1  Output: -1

Example 2

  public class IntegerCompareUnsignedExample2 {  public static void main(String[] args) {  //compares two Integer values numerically        Integer x = 98;        Integer y= -8;        int retResult =  Integer.compareUnsigned(x,y);            if(retResult > 0) {           System.out.println(“x is greater than y”);        } else if(retResult< 0) {           System.out.println(“x is less than y”);        } else {           System.out.println(“x is equal to y”);        }  }  }  

Test it Now

Output:

x is greater than y

Example 3

  import java.util.Scanner;  public class IntegerCompareUnsignedExample3 {  public static void main(String[] args) {  //Ask the input from user  System.out.print(“Enter the first value: “);  Scanner sc = new Scanner(System.in);  int val1 = sc.nextInt();  System.out.print(“Enter the second value: “);  int val2 = sc.nextInt();  // compare the two user input (unsigned value)  int result = Integer.compareUnsigned(val1, val2);  // Print the output  if(result == 0){  System.out.println(“They are equal”);  }else if(result > 0){  System.out.println(“First Value is greater than the second value.”);  }else{  System.out.println(“First Value is less than the second value.”);  }  sc.close();        }  }  

Test it Now

Output:

Enter the first value: -45  Enter the second value: 65  First Value is greater than the second value.

Example 4

  import java.util.Scanner;  public class IntegerCompareUnsignedExample4 {  public static void main(String[] args) {  Scanner sc = new Scanner(System.in);              System.out.println(“Campare the user inputs (unsigned integer): “);              Integer val1 = sc.nextInt();              Integer val2 = sc.nextInt();              Integer val3 = sc.nextInt();              sc.close();              System.out.println(“The Results are: “);              System.out.println(Integer.compareUnsigned(val1,val2));              System.out.println(Integer.compareUnsigned(val1,val3));              System.out.println(Integer.compareUnsigned(val3,val2));  }  }  

Test it Now

Output:

Campare the user inputs (unsigned integer):   -44  -44  88  The Results are:   0  1  -1
