Java源字符串中删除指定字符串,使得最终结果不包含子字符串,记录删除次数?

Question

源字符串例如:123java123jajajavavava123java
要删除的字符串:java
最终结果123123123 count=5.
请问这是怎么实现的啊???

Answer 1

String s1 = "123java123jajajavavava123java";
String s2 = "java";
String result = s1;
while(result.contains(s2)){
result = result.replace(s2,"");
System.out.println(result);

    }
    int count = (s1.length() - result.length()) / s2.length();
    System.out.println(count);
