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 read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
