Convert Integer to Octal String in Java

The Integer.toOctalString() method in Java converts int to octal string.

Let’s say the following are our integer values.

int val1 = 9;
int val2 = 20;
int val3 = 2;

Convert the above int values to octal string.

Integer.toOctalString(val1);
Integer.toOctalString(val2);
Integer.toOctalString(val3);

Example

 Live Demo

public class Demo {
   public static void main(String[] args) {
      int val1 = 9;
      int val2 = 20;
      int val3 = 30;
      int val4 = 78;
      int val5 = 2;
      System.out.println("Converting integer "+val1+" to Octal String:       "+Integer.toOctalString(val1));
      System.out.println("Converting integer "+val2+" to Octal String: "+Integer.toOctalString(val2));
      System.out.println("Converting integer "+val3+" to Octal String: "+Integer.toOctalString(val3));
      System.out.println("Converting integer "+val4+" to Octal String: "+Integer.toOctalString(val4));
      System.out.println("Converting integer "+val5+" to Octal String: "+Integer.toOctalString(val5));
   }
}

Output

Converting integer 9 to Octal String: 11
Converting integer 20 to Octal String: 24
Converting integer 30 to Octal String: 36
Converting integer 78 to Octal String: 116
Converting integer 2 to Octal String: 2
