Octal integer literal (To indicate octal, prefix the literal with 0 (zero)) : Integer « Java Source And Data Type « SCJP






Octal integers use only the digits 0 to 7. 


public class MainClass{
    
  public static void main(String[] argv){
    int intValue = 034;  // 28 in decimal

    int six = 06; // Equal to decimal 6
    int seven = 07; // Equal to decimal 7
    int eight = 010; // Equal to decimal 8
    int nine = 011; // Equal to decimal 9
   
    
    System.out.println("Octal 010 = " + eight);
    
  }

}
Octal 010 = 8
