How to convert integer into float in Java?

To convert an int into a float in Java, you can simply assign the int value to a float variable or use a cast to explicitly perform the conversion. Here are two common ways to convert an int to a float:

  1. Implicit Conversion (Widening Conversion):

    • Java allows implicit conversion from int to float because the float type can represent a wider range of values (including decimal fractions) compared to int. When you assign an int value to a float variable, Java automatically performs the conversion.
    int intValue = 42; float floatValue = intValue; // Implicit conversion

    In this example, intValue is implicitly converted to a float when assigned to floatValue.

  2. Explicit Conversion (Casting):

    • You can also explicitly convert an int to a float using casting. This is useful when you want to make the conversion clear in your code.
    int intValue = 42; float floatValue = (float) intValue; // Explicit conversion using casting

    In this case, (float) is used to cast intValue to a float. This ensures that the conversion is explicitly performed.

Both methods result in a float variable containing the converted value of the int. You can then use the float variable in calculations involving decimal fractions.
