Why storing a literal value which is whole number in nature in a Float datatype in java without 'f' at the end don't give an error?

float firstFloatValue = 5;

float secondFloatValue = 2.5;

Why is that the first variable without an f at the end doesn't give an error while the second variable does? I know that if we don't put an f at the end of the literal, it is assumed as a double. But why there is not an error while initializing the first variable by 5 without an f at the end. Please help me, I am very new to Java.

Error message: 

Main.java:12: error: incompatible types: possible lossy conversion from double to float
        float secondFloatValue = 2.5;

Because of type casting firstFloatValue example int is type casted to float ( small memory data types into higher memory data types ) default behaviour. But in second double cant be type casted to float

You didn't include the error message (ALWAYS include the error message on StackOverflow).

Without the type suffix f (as in 2.5f) the literal 2.5 is interpreted as a double, which does not fit in a float variable.
