[java] Convert string to float?

Just as title says. I don't believe it is possible to do this but if it is let me know.

This is needed for a bukkit (minecraft server) plugin I'm writing. I want to take a command: tnt [power]. Where power is the string returned that I want to convert to float.


This question is related to java

The answer is

Use Float.valueOf(String) to do the conversion.

The difference between valueOf() and parseFloat() is only the return. Use the former if you want a Float (object) and the latter if you want the float number.

public class NumberFormatExceptionExample {
private static final String str = "123.234";
public static void main(String[] args){
float i = Float.valueOf(str); //Float.parseFloat(str);
System.out.println("Value parsed :"+i);

This should resolve the problem.

Can anyone suggest how should we handle this when the string comes in 35,000.00

Try this:

String numberStr = "3.5";
Float number = null;
try {
   number = Float.parseFloat(numberStr);
} catch (NumberFormatException e) {
    System.out.println("numberStr is not a number");

String s = "3.14";
float f = Float.parseFloat(s);

Try this:

String yourVal = "20.5";
float a = (Float.valueOf(yourVal)).floatValue(); 

Using Float.parseFloat()?

class Test {
    public static void main(String[] args) {
        String s = "3.14";
        float f = Float.parseFloat(s);
