This post shows how you can convert float to String in Java.
Converting float to String using Float.toString() method
Wrapper class Float in Java has a toString() method that returns a string representation of the passed float argument.

public class FloatToString { public static void main(String[] args) { float val = 28.92f; String strVal = Float.toString(val); System.out.println("Converted String value = " + strVal); } } |
Output
|
1 |
Converted String value = 28.92 |
Convert using String.valueOf() method
String.valueOf(float f)– Returns the string representation of the float argument.

public class FloatToString { public static void main(String[] args) { float val = 28.92f; String strVal = String.valueOf(val); System.out.println("Converted String value = " + strVal); } } |
Output
|
1 |
Converted String value = 28.92 |
Converting using String concatenation
You can concatenate the float value with an empty string (“”) that will return the result as a String. That’s one way to convert float to String
|

public class FloatToString { public static void main(String[] args) { float val = 108.256f; String strVal = val + ""; System.out.println("Converted String value = " + strVal); } } |
Output
|
1 |
Converted String value = 108.256 |
Converting using append method of StringBuilder or StringBuffer class
Both StringBuilder and StringBuffer classes have append() method where you can pass float as an argument. The append() method will append the string representation of the float argument to the sequence.

public class FloatToString { public static void main(String[] args) { float val = -49.12f; StringBuilder sb = new StringBuilder(); sb.append(val); System.out.println("Converted String value = " + sb.toString()); } } |
Output

1 |
Converted String value = -49.12 |
