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.
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'); } }
