Java Byte compareTo() method

The compareTo() method of Java Byte class compares two Byte objects numerically

Syntax:

Parameters:

The parameter ‘anotherByte’ represents the Byte to be compared.

Specified by

This method is specified by compareTo in interface Comparable<Byte>

Return Value

This method returns an integer value.

It returns zero, if this Byte is equal to the parameter.
It returns positive one, if this Byte is numerically greater than the argument Byte.
It returns negative one, if this Byte is numerically smaller than the argument Byte.

Example 1

  public class JavaByteCompareToExample1 {      public static void main(String[] args) {          Byte byte1=127;          Byte byte2=67;          //It compares two Byte objects numerically          int val=byte1.compareTo(byte2);          if(val==0){              System.out.println(byte1+” and “+byte2+” values are equal.”);          }          else if(val>0){              System.out.println(byte1+” is greater than “+byte2+” .”);          }          else{              System.out.println(byte2+” is greater than “+byte1+” .”);          }      }  }  

Test it Now

Output:

127 is greater than 67 .

Example 2

  import java.util.Scanner;  public class JavaByteCompareToExample2 {      public static void main(String[] args) {          Byte byte1=18;          Scanner scanner=new Scanner(System.in);          System.out.print(“Enter your age : “);          byte byte2=scanner.nextByte();          int val=byte1.compareTo(byte2);          if (val<0){              System.out.println(“Congratulations! You are an adult. Now you can vote.”);          }          else {              int byte3=byte1-byte2;              System.out.println(“Oops! You are not an adult. You can vote after “+ byte3+” years.”);          }      }  }  

Output:

Enter your age : 24  Congratulations! You are an adult. Now you can vote.

Example 3

  public class JavaByteCompareToExample3 {      public static void main(String[] args) {          //byte value should be in the range between -127 to 128          Byte b1= 567;          byte b2=Byte.MIN_VALUE;          int val=b1.compareTo(b1);          if(val>0){              System.out.println(b1+” is greater than “+b2);          }          else{              System.out.println(b2+” is greater than “+b1);          }      }  }  

Test it Now

Output:

Error:(5, 18) java: incompatible types: int cannot be converted to java.lang.Byte
