Java Float toString() Method

The toString() method of Java Float class returns a string illustration of this Float.

The primitive float value that corresponds to this Float is converted to a String same as done by toString() method of one argument.

Syntax:

Parameters:

Return Value:

The toString() method returns a String illustration of this Float object.

Example 1

    public class FloatToStringExample1 {        public static void main(String[] args) {            Float f1=9876f;            System.out.println(“1. “+f1+” Converted to String = “+f1.toString());            Float f2=1001f;            System.out.println(“2. “+f2+” Converted to String = “+f2.toString());           // instead of adding it will concatenate the two strings            String f3=f1.toString()+f2.toString();            System.out.println(“3. Concatenated String = “+f3);        }    }  

Test it Now

Output:

1. 9876.0 Converted to String = 9876.0  2. 1001.0 Converted to String = 1001.0  3. Concatenated String = 9876.01001.0

Example 2

  import java.util.Scanner;      public class FloatToStringExample2 {        public static void main(String[] args) {            Scanner scanner=new Scanner(System.in);            System.out.print(“Enter your password:”);            Float f1 =scanner.nextFloat();            //calling static toString() method            String f2 = Float.toString(f1);            System.out.println(“Your password + 18 = “+f2+18);      }  }  

Test it Now

Output:

Enter your password:923  Your password + 18 = 923.018

Example 3

  public class FloatToStringExample3 {      public static void main(String[] args) {          int f1 = Float.MIN_EXPONENT;          int f2 = Float.MAX_EXPONENT;          String f3 = Float.toString(f1)+Float.toString(f2);          System.out.println(“1. Sum =  “+f3);          System.out.println();          Float f4=Float.NEGATIVE_INFINITY;          System.out.println(“String value = “+f4.toString());          Float f5= Float.MAX_VALUE;          System.out.println(“String value = “+f5.toString());          String s2 = f4.toString()+f5.toString();          System.out.println(“2. Sum = “+s2);     }  }  

Test it Now

Output:

1. Sum =  -126.0127.0    String value = -Infinity  String value = 3.4028235E38  2. Sum = -Infinity3.4028235E38
