Java Float compare() method

The compare() method of Java Float class compares the two specified float values i.e. f1 and f2.

Syntax:

Parameters:

The parameters passed are f1(the first float value) and f2(the second float value).

Return Value:

This method returns the integer value of the argument.

Returns a zero if value of f1 is same as value of f2(f1 = f2).
Return a positive value if f1 is greater than f2(f1 > f2).
Return a negative value if f1 is less than f2(f1 ).>

Example 1

  import java.lang.Float;      public class FloatcompareMethodExample1 {        public static void main(String[] args) {              Float f1 = new Float(“10”);          Float f2 = new Float(“50.44″);            // comparing f1 and f2          int compare=Float.compare(f1 , f2);            if(compare > 0){                System.out.println(f1+” is greater and “+f2+” is smaller.”);          }            else if(compare<0){                System.out.println(f1+” is smaller “+f2+” is greater.”);          }          else{                System.out.println(” Both are equal! “);          }      }  }  

Test it Now

Output:

10.0 is smaller 50.44 is greater.

Example 2

  import java.lang.Float;      public class FloatcompareMethodExample2 {        public static void main(String[] args) {              Float f1 = new Float(“10″);              // comparing f1 and f2          int compare=Float.compare(f1 );            if(compare > 0){                System.out.println(f1+” is greater .”);          }            else if(compare<0){                System.out.println(f1+” is smaller .”);          }          else{                System.out.println(” Both are equal! “);          }      }  }  

Test it Now

Output:

Error:(13, 26) java: method compare in class java.lang.Float cannot be applied to given types;    required: float,float    found: java.lang.Float    reason: actual and formal argument lists differ in length

It is compulsory to pass two arguments in Float class compare() method otherwise, it will give you an error.
