Can't figure out how to replace a string with a character in Java. I wanted a function like this:
replace(string, char)
but there's not a function like this in Java.
String str = str.replace("word", '\u0082');
String str = str.replace("word", (char)130);
How do I go about this?
Use a string as the replacement that happens to be only a single character in length:
String original = "words";
String replaced = original.replace("word", "\u0130");
The replaced instance will be equivalent to "İs".
Note also that, from your question, '\u0130' and (char)130 are not the same characters. The \u syntax uses hexadecimal and your cast is using decimal notation.
"word" is replaced by a single character, leaving the remaining characters alone. I'm not going to edit my post at this time because I have nothing to add to it. Thank you for considering to change your vote; next time, please don't be so quick to downvote other answers that may be helpful even if you don't think they're perfect.Very simply:
String orginal = "asdf";
char replacement = 'z';
orginal = original.replace(original, replacement+"");
original String.original = "" + replacement; without a helper method?String.replace(String, char) does not exist in the Java API.You asked for a "function" in Java, you can allways create a method like this
public static String replace (String text, char old, char n){
return text.replace(old, n);
}
Then you can call this method as you want
String a = replace("ae", 'e', '3');
In this case the method will return a String with a3 as value, but you can replace not only a char by another, you can replace a String with multiple characters in the same way
public static String replace (String text, String old, String n){
return text.replace(old, n);
}
Then you call this method like this
String a = replace("aes", "es", "rmy");
The result will be a String with army as value
char in the second parameter for the new one in the third parameter, if he wants replace the whole 'String' for a 'char' there's no need for a 'method', only an assignment will work i.e.: String a='a'+"" :)method he can do exactly the same setting as the second parameter the original String and a String with lenght of 1 i.e.: String a="aes";a=replace(a, a, "e");, the result will be a String with a value of e, and with this he will not lose the original functionality of the methodthe simplest way:
"value_".replace("_",String.valueOf((char)58 )); //return "value:"
EDIT:
(char)58 //return: ':'
(int)':' //return: 58
Since we want to work with codes and no character we have to pass code to character
another problem to solve is that method "replace" does not take "(String x,char y)"
So we pass our character to String this way:
String.valueOf((char)58) //this is a String like this ":"
Finally we have String from int code, to be replaced.
"String is a sequence of characters"
String s="hello";
char c='Y';
System.out.println(s.replace(s, Character.toString(c)));
Output:
Y
s.replace(s, foo) is a complicated way of writing foo. Using the String replace method makes sense when used with substrings.
chara String? Example:str.replace("word", "" + '\u0130');
