Java program to display printable characters

To display printable characters, you need to use32to127between ASCII values.

So, we use the following instead of System.out.println()

System.out.write();

The following displays all printable characters.

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

Let's see the complete example.

Example

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('\n');
         else
         System.out.write('\t');
      }
      System.out.write('\n');
   }
}
