In java ,float a =1.1f; what is this f stands for??
In java, when a value is assigned to a float. like float a = 1.1f; why we are putting the f at the last of the assigned value.

f tells the compiler that your variable type is float not a double.
float x = 3.14f;
double y = 3.14;
+ 13
If you ignore that f, compiler does an implicit conversion between types. (that is not a good practice in programming- at least in C++)

by default, Java will treat 1.1 as a double, not a float

Java won't implicitly cast to a float because double has higher precision. you could also write
float f = (float) 3.14
but it won't work if you don't explicitly tell it to do so

you're declaring the variable to be of type 'float', but not doing anything to the value itself. Java will treat it as a double by default, and this can least to unexpected errors
