float Datatype in Java
Float data type is a single-precision 32-bit IEEE 754 floating point
Float is mainly used to save memory in large arrays of floating point numbers
Default value is 0.0f
Float data type is never used for precise values such as currency
Example: float f1 = 234.5f
public class FloatDataType {
public static void main(String []args) {
// this is declaration and initialization of variable a
// datatype is float
float a = 234.5f;
// this is declaration and initialization of variable b
// datatype is float
float b = 234.565f;
System.out.println(a); // it will print a variable
System.out.println(b); // it will print b variable
}
}
234.5
234.565

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
