You are to write a program which converts text containing double-quote (") characters into text that is identical except that double-quotes have been replaced by the two-character sequences required by TeX for delimiting quotations with oriented double-quotes. The double-quote (") characters should be replaced appropriately by either `` if the " opens a quotation and by '' if the " closes a quotation. Notice that the question of nested quotations does not arise: The first " must be replaced by ``, the next by '', the next by ``, the next by '', the next by ``, the next by '', and so on.
Input will consist of several lines of text containing an even number of double-quote (") characters. Input is ended with an end-of-file character. The text must be output exactly as it was input except that: - the first " in each pair is replaced by two ` characters: `` and
- the second " in each pair is replaced by two ' characters: ''.
For this problem , you can try to resolve with this algorithm
- First of all you must identify an EOF input scanner
- Split string into some substring, for example i try with loop one by one (if you know better you can use it)
- Identify a variable as a sign of the first pair or the second one , i use a boolean variable
- Test substring if contains " (double quoted) and replace them with `` for the first and '' for the second
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner inp=new Scanner(System.in);
boolean ganjil=true;
while(inp.hasNext()){
String str=inp.nextLine();
if(str.isEmpty()) break;
for (int i = 0; i < str.length(); i++) {
String a=str.substring(i, i+1);
if(a.contains("\"")){
if(ganjil) {
a = a.replaceFirst("\"", "``");
ganjil=false;
}else{
a = a.replaceFirst("\"", "''");
ganjil=true;
}}
System.out.print(a);
}
System.out.println("");
}
}
}
