Help Please...Converting int to char
hello. Im a bit stuck here, i need to convert some code from int values to char values. what my program should do is accept character input (one letter at a time) and store it into a list. this list has then got to be sorted and then broken into two halfs using the merge sort algorithm, then i have to merge the list together. i am not sure how to sort the input alphabetically, i just know how to sort numbers. i have the code for numbers
publicclass IntegerObjectimplements Comparable{
privateint myInteger;
// Constructor for IntegerObject
public IntegerObject(int i){
this.myInteger = i;
}
// Get the integer encapsulated by the IntegerObject
publicint getMyInteger(){
return this.myInteger;
}
// Set the integer to be encapsualted by the IntegerObject
publicvoid setMyInteger(int i){
this.myInteger = i;
}
// Print integers encapsulated by the IntegerObject
public String toString(){
return" " + myInteger;
}
// Check if the contents of one object (integer) matches the contents of another
publicboolean equals (Object e){
if ((einstanceof IntegerObject) && (((IntegerObject)e).getMyInteger() == this.getMyInteger())){
returntrue;
}
elsereturnfalse;
}
// Compare the contents of one object (integer) with the content of another
publicint compareTo(Object e){
int aValue = this.myInteger;
int anotherValue = ((IntegerObject)e).myInteger;
return (aValue<anotherValue ? -1 : (aValue==anotherValue ? 0 : 1));
}
}
what i want to do it change that to char.
hope someone can help me. thanks :-)>
This code I wrote for a cryptography program can help. It converts an incoming String into numbers and can convert the string of numbers back into the original string. A few alterations and you have your solution.
public class y2k {
String message = "";
public y2k(String message) {
this.message = message;
}
public String getEncoded() {
String u = "";
//Get rid of the unwanted numbers
message = message.trim();
char[] chars = new char[message.length()];
for(int i = 0; i < message.length(); i++) {
chars[i] = message.charAt(i);
u = u + " " + chars[i];
}
u = u.toLowerCase();
String[] eye = u.split(" ");
String giver = "";
for(int i = 0; i < eye.length; i++) {
if(eye[i].contains("a")) giver = giver + " " + 89;
