How to remove a substring from a string without using replace() method?
问题
String string = "yesnoyesnoyesnoyesno";
String substring = "no";
如何将字符串中的每个子字符串删除，以使得最终结果为 "yesyesyesyes"？
英文:
String string = "yesnoyesnoyesnoyesno";
String substring = "no";
How do I remove every occurrence of the substring from the string so it ends up being "yesyesyesyes"?

如果您使用的是Java 8或更高版本，则可以尝试在"no"上拆分输入，然后将生成的数组组合成一个字符串：
String string = "yesnoyesnoyesnoyesno";
string = String.join("", string.split("no"));
System.out.println(string);
这将打印：
yesyesyesyes
英文:
If you are using Java 8+, then you could try splitting the input on "no" and then joining the resulting array together into a string:
String string = "yesnoyesnoyesnoyesno";
string = String.join("", string.split("no"));
System.out.println(string);
This prints:
yesyesyesyes

这并未使用replace()，所以从技术上讲它满足要求：
String str = string.replaceAll("no", "");
英文:
This doesn't use the replace(), so technically it meets the brief:
String str = string.replaceAll("no", "");

String input = "yesnoyesnoyesno";
String output = "";
for (String token : input.split("no"))
output = output.concat(token);
System.out.println(output);
英文:
String input = "yesnoyesnoyesno";
String output="";
for(String token : input.split("no") )
output = output.concat(token);
System.out.println(output);
It prints:
yesyesyesyes
