An integer literal without a suffix L or l is regarded as an int. Therefore, the following will generate a compile error because 9876543210 is larger than the capacity for an int:
long a = 9876543210;
To rectify the problem, add an L or l at the end of the number like this:
long a = 9876543210L; - DARцитирапреди 8 годиниLiterals
From time to time you need to assign values to variables in your program, such as number 2 to an int or the character ‘c’ to a char. For this, you need to write the value representation in a format that the Java compiler understands. This source code representation of a value is called literal. There are three types of literals: literals of primitive types, string literals, and the null literal.
