You asked: What does 1000L mean in Java?

What is 100L in Java?

In Java, the int data type is considered as default data type for integers. … And if you want Java to create an eight- byte memory area to store 100, you have to write 100L. (long is an eight-byte integer type, introduced in the following section).

What is 1L in Java long?

By default value 2147483647 is considered by java compiler is int type. Internal type casting is done by compiler and int is auto promoted to Long type. long l = 2147483648; //CE: value is treated as int but out of range.

What is 10L in Java?

When you type “return 10L” it means that you are telling the compiler that the value want returned is a long integer (32-bit) as opposed to int (16-bit).

What is difference between float and double in Java?

Double takes more space but more precise during computation and float takes less space but less precise. According to the IEEE standards, float is a 32 bit representation of a real number while double is a 64 bit representation. In Java programs we normally mostly see the use of double data type.

How long is represented in Java?

The long contains minimum value of -263 and a maximum value of 263-1. Its default value is 0L. Its default size is 8 byte. It is used when you need a higher range integer value.
