I made some modifications with Tech_guy code: A more brute way to display the results according to the question would be: public class AsciiPrinter { public static void main(String[] args) { for (int i = 32; i <= 126; i+=5){ System.out.println( i + ": " + (char)i + " \t" + (i+1) + ": " + (char)(i+1) + " \t" + (i+2) + ": " + (char)(i+2) + " \t" + (i+3) + ": " + (char)(i+3) + " \t" + (i+4) + ": " + (char)(i+4)); } } } And the output Results will look like (Five column pairs separated by a tab): 32: 33: ! 34: " 35: # 36: $ 37: % 38: & 39: ' 40: ( 41: ) 42: * 43: + 44: , 45: - 46: . 47: / 48: 0 49: 1 50: 2 51: 3 52: 4 53: 5 54: 6 55: 7 56: 8 57: 9 58: : 59: ; 60: < 61: = 62: > 63: ? 64: @ 65: A 66: B 67: C 68: D 69: E 70: F 71: G 72: H 73: I 74: J 75: K 76: L 77: M 78: N 79: O 80: P 81: Q 82: R 83: S 84: T 85: U 86: V 87: W 88: X 89: Y 90: Z 91: [ 92: \ 93: ] 94: ^ 95: _ 96: ` 97: a 98: b 99: c 100: d 101: e 102: f 103: g 104: h 105: i 106: j 107: k 108: l 109: m 110: n 111: o 112: p 113: q 114: r 115: s 116: t 117: u 118: v 119: w 120: x 121: y 122: z 123: { 124: | 125: } 126: ~ Happy Programming :)
