Java Program to display printable characters

To display printable characters, you need to work with the ASCII values from 32 to 127.

With that, we are using the following, instead of System.out.println()

System.out.write();

The following displays all the printable characters.

for (int i = 32; i < 127; i++) {
System.out.write(i);

Let us see the complete example.

Example

 Live Demo

public class Demo {
   public static void main(String []args) {
      System.out.println("Printable characters...");
      for (int i = 32; i < 127; i++) {
         System.out.write(i);
         if (i % 8 == 7)
         System.out.write('
');
         else
         System.out.write('\t');
      }
      System.out.write('
');
   }
}

Output
