Using Java’s Float class.
float f = Float.parseFloat("25");
String s = Float.toString(25.0f);
To compare it's always better to convert the string to float and compare as two floats. This is because for one float number there are multiple string representations, which are different when compared as strings (e.g. "25" != "25.0" != "25.00" etc.)

July 12, 2025 - Strings - Strings in Java are objects that are supported internally by a char array. Since arrays are immutable, and strings are also a type of exceptional array that holds characters, therefore, strings are immutable as well. Float - The float data type is a single-precision 32-bit IEEE 754 floating-point. Its value range is unlimited. Using a float (instead of double) is suggested if you need to save memory in large arrays of floating-point numbers.

Stupid roundabout way of doing it:
float myFloat = 33.33f;
int tenTimesFloat = (int) (myFloat * 10); // 333
String result = (tenTimesFloat / 10) + "." + (tenTimesFloat % 10); // 33.3
Note that this truncates the number, so 10.99 would convert to 10.9. To round, use Math.round(myFloat * 10) instead of (int) (myFloat * 10). Also, this only works for float values that are between Integer.MAX_VALUE/10 and Integer.MIN_VALUE/10.
