How to convert String to Float in Java ?

Answer

To convert a string to float in Java, you can use the 'parseFloat()' method of the Float class.

✐ Examples

1 Convert "3.14" String to Float

In this example,

We create a string variable str1 with a value of "3.14".
We convert the string to a float using the parseFloat() method of the Float class and store the result in a variable float1.
Finally, we print the float value float1 to the console.

Java Program

// Convert "3.14" String to Float
public class Main {
    public static void main(String[] args) {
        String str1 = "3.14";
        float float1 = Float.parseFloat(str1);
        System.out.println("Float value is: " + float1);
    }
}

Output

Float value is: 3.14

2 Convert "10.5" String to Float

In this example,

We create a string variable str2 with a value of "10.5".
We convert the string to a float using the parseFloat() method of the Float class and store the result in a variable float2.
Finally, we print the float value float2 to the console.

Java Program

// Convert "10.5" String to Float
public class Main {
    public static void main(String[] args) {
        String str2 = "10.5";
        float float2 = Float.parseFloat(str2);
        System.out.println("Float value is: " + float2);
    }
}

Output

Float value is: 10.5
