In Java, we can convert String to float in couple of different ways.

Short solutions:

xxxxxxxxxx
 
// solution 1
float num1 = Float.parseFloat("123.45");
​
// solution 2
Float num2 = Float.valueOf("123.45");
​
// solution 3
Float num3 = new Float("123.45");

1. Using Float.parseFloat()

Edit

xxxxxxxxxx
 
public class Example1 {
​
    public static void main(String[] args) {
        String str = "123.45";
        float num = Float.parseFloat(str);
        System.out.println(num); // 123.45
    }
}

Output:

xxxxxxxxxx
 
123.45

2. Using Float.valueOf()

Edit

xxxxxxxxxx
 
public class Example2 {
​
    public static void main(String[] args) {
        String str = "123.45";
        Float num = Float.valueOf(str);
        System.out.println(num); // 123.45
    }
}

Output:

xxxxxxxxxx
 
123.45

3. Using constructor - new Float(String s)

Edit

xxxxxxxxxx
 
public class Example3 {
​
    public static void main(String[] args) {
        String str = "123.45";
        Float num = new Float(str);
        System.out.println(num); // 123.45
    }
}

Output:

xxxxxxxxxx
 
123.45

4. Using DecimalFormat parse method

Edit

xxxxxxxxxx
 
import java.text.DecimalFormat;
import java.text.ParseException;
​
public class Example4 {
​
    public static void main(String[] args) throws ParseException {
        String str = "123.45";
        float num = DecimalFormat.getNumberInstance().parse(str).floatValue();
        System.out.println(num); // 123.45
    }
}

Output:

xxxxxxxxxx
 
123.45
