Java Float intValue() Method

The intValue() method of Java Float class returns the integer value of this Float Object by simply narrowing primitive conversion.

Syntax:

Parameters:

Return Value:

This method returns an int value for this float object.

Example 1

public class FloatIntValueExample1 {
    public static void main(String[] args) {
        Float f1 = new Float(67.009);
        Float f2 = new Float(0.789);
        Float f3= f1*f2;
        System.out.println("Multiplication of float values, "+f1+"*"+f2+" = "+f3 );
        //converting float into int
        int f4=f1.intValue()*f2.intValue();
        System.out.println("Multiplication of integer values, "+f1+"*"+f2+" = "+f4 );
    }
    
}

Test it Now

Output:

Multiplication of float values, 67.009*0.789 = 52.870102
Multiplication of integer values, 67.009*0.789 = 0

Example 2

import java.util.Scanner;

public class FloatIntValueExample2 {
    public static void main(String[] args) {
        Scanner scanner= new Scanner(System.in);
        System.out.println("Enter the number to be reversed");
        Float f1 = scanner.nextFloat();
         int num = f1.intValue();
        System.out.println("Integer value = "+num);

        int rev_num=0;
        while(num>0){
            rev_num =rev_num*10 + num%10;
            num = num/10;
            }
        System.out.println("Reversed int number = "+rev_num);
    }
}

Test it Now

Output:

Enter the number to be reversed
78.90
Integer value = 78
Reversed int number = 87

Example 3

import java.util.Scanner;

public class FloatIntValueExample3 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your marks in english");
        Float f1 = scanner.nextFloat();
         Float val1= f1 % f1.intValue();

        if(val1 >= 0.5) {
            int val2=f1.byteValue()+1;
            System.out.println("Marks after rounding off  : "+val2);
        }
        else{
            System.out.println("Marks after rounding off : "+f1.byteValue());
        }


    }

}

Test it Now

Output:

Enter your marks in english
89.99
Marks after rounding off  : 90

Example 4

public class FloatIntValueExample4 {
    public static void main(String[] args) {
        float f1 =4656f;
        Float f2= new Float(f1);
        Float f3=new Float(678.89);
        Float f4=f2.intValue()- f3.intValue();
        System.out.println("Value after subtraction = "+f4);

    }
}

Test it Now

Output:

Error:(8, 31) java: incompatible types: int cannot be converted to java.lang.Float

Here, we are converting float (f2) into integer by intValue() method and without an explicit cast, we are placing it into float (f4). Either we should put it into int or should directly call this method in println function otherwise, we will get an error.
