JAVA Programming

1. Program Description: This method will insert spaces in front of a string and return the new string. The number of spaces to insert and the string itself will be passed in as parameters.

BEGIN setLeft (number of spaces, string)

FOR (each space to be inserted)

add a space to be beginning of the string

END FOR

return the new string with the leading spaces

END setLeft

public static String setLeft(int num, String word)

 {

 //local constants

 //local variables

 /*******************************************************/

 for (int i = 0;i < num;i++)

 word = " " + word;

 return word;

 }

2. Program Description: This method will insert spaces in front of a string and return the new string. The number of spaces will be determined by the field width and the length of the string (Width - Length).If the string is wider than the field width, no spaces will be added to the front of the string

 BEGIN setRight (field width, string)

 Find the length of the string

 Calc the number of spaces to be added

 IF (there is room to add spaces)

 FOR (each space to be added)

 add a space to the front of the string

 END FOR

 END IF

 return the string

public static String setRight(int width, String word)

 {

 //local constants

 //local variables

 int len = word.length(); //get the string length

 int pad = width - len; //how many spaces to add to front of string

 /*******************/

 //if there is room to add sapces

 if (len < width)

 //add the spaces to the front of the string

 for (int i = 0; i < pad; i++)

 word = " " + word;

 //return the string

 return word;

 }
