I have strings in array I want to split them into char array? is it possible??
I did this:
// skipped the portion of code
void somefunction(String[] gf){
char[] charArrays = new char[500];
charArrays = gf.toCharArray(); // not allowing to use toCharArray
// skipped the portion of code
}
gf is a String[]. You can apply the method in a single String instead:
for (String s : gf) {
charArrays = s.toCharArray();
}
Here's a more concrete example of what you want/need to achieve (IMO):
void somefunction(String[] gf) {
List<char[]> data = new ArrayList<char[]>();
int wholeSize = 0;
for (String s : gf) {
char[] charArray = s.toCharArray();
data.add(charArray);
wholeSize += charArray.length;
}
char[] wholeStringIntoCharArray = new char[wholeSize];
int i = 0;
for (char[] charArray : data) {
for (char c : charArray) {
wholeStringIntoCharArray [i++] = c;
}
}
//return wholeStringIntoCharArray;
}
int size = 0;
for (String s : input) {
size += s.length();
}
char[] output = new char[size];
int start = 0;
for (String s : input) {
System.arraycopy(s.toCharArray(), 0, output, start, s.length());
start+=s.length();
}
Here's a shorter version:
String[] stringArray = new String[]{"abc", "qwe", "www"};
List<Character> charList = new ArrayList<Character>();
for (String string : stringArray) {
for (char ch : string.toCharArray()) {
charList.add(ch);
}
}
Character[] finalArray = charList.toArray(new Character[0]);
You wrote this: I have strings in array I want to split them into char array? is it possible??
YES it is possible. You must join first and then split in an array of characters. try the following:
String result = ("" + Arrays.asList(gf)).replaceAll("(^.|.$)", "").replace(", ", "" );
char[] charArrays = result.toCharArray();
char[] charArrays = new char[500];charArrays = gf.toCharArray();I know where the perfomance gain of new processors goes.
