Numbers in Java (With 0 Prefix and with Strings)
Consider the following Java program.
import java.io.*;
class GFG
{
public static void main (String[] args)
{
int x = 012 ;
System.out.print(x);
}
}
|
Output:
10
The reason for above output is, when a 0 is prefixed the value is considered octal, since 12 in octal is 10 in decimal, the result is 10. Similarly, if i = 0112, result will be 74 (in decimal). This behavior is same as C/C++ (see this).
Also,
import java.io.*;
class GFG
{
public static void main (String[] args)
{
String s = 3 + 2 + "hello" + 6 + 4 ;
System.out.print(s);
}
}
|
Output :
5hello64
Java takes the numbers before the strings are introduced as int and once the string literals are introduced, all the following numbers are considered as strings.
