Computer manufacturers agreed to use one code called the ASCII (American Standard Code for Information Interchange).There are 128 standard ASCII characters, numbered from 0 to 127. Extended ASCII adds another 128 values and goes to 255. The ASCII values to print using to the for loop. A for loop is a repetition control structure which allows us to write a loop that is executed a specific number of times. The three components of the for loop (separated by ;) are variable declaration/initialization , the condition , and the increment statement.

Codes 32-127 are common for all the different variations of the ASCII table, they are called printable characters, represent letters, digits, punctuation marks, and a few miscellaneous symbols. 65-90 A-Z 97-122 a-z 48-57 0-9 Space 32 */ for(int i=65;i<=90;i++) { System.out.println(i+" "+(char)i); } } }
