Java Floating-point Literals

In Java, a floating-point literal is a numeric value with a decimal point that represents a value of the float or double data type.

Here are some examples of floating-point literals in Java:

public class Main {
  public static void main(String[] args) {
    float value1 = 3.14f;  // The "f" suffix indicates that the value is a float
    double value2 = 3.14;  // The default data type for decimal values is double
    double value3 = 6.022e+23;  // The "e" notation indicates scientific notation
  }
}

In the first example, the value 3.14 is assigned to a float variable. The f suffix indicates that the value is a float literal and should be treated as a float value.

In the second example, the value 3.14 is assigned to a double variable. The default data type for decimal values in Java is double, so no suffix is needed.

In the third example, the value 6.022e+23 is assigned to a double variable. The e notation indicates scientific notation, and the +23 exponent indicates that the value should be multiplied by 10 to the power of 23.

You can use floating-point literals to represent decimal values in your Java programs. Just be aware that the float data type has less precision than the double data type, so you may want to use the double data type if you need greater precision.
