Java performs an automatic type conversion when storing a literal integer constant into variables of type byte, short, or long.
public class Main {
public static void main(String[] argv) {
byte b = 1;
}
}
But you cannot store a value out of the byte scope
public class Main{
public static void main(String[] argv){
byte b = 11111;
}
}
When compiling, it generates the following error message:
D:\>javac Main.java
Main.java:3: possible loss of precision
found : int
required: byte
byte b = 11111;
^
1 error
