统计跟“string”相同的字符串有多少个，（Str3.java） {“string”,“starting”,“string”,“street”,“soft”}count++

可以使用一个计数器变量，遍历字符串数组，判断每个字符串是否与目标字符串"string"相同，如果相同则计数器加1。最后输出计数器的值即可。

可以参考下面的代码实现：

public class Str3 {
    public static void main(String[] args) {
        String[] arr = {"string", "starting", "string", "street", "soft"};
        String target = "string";
        int count = 0;

        for (String str : arr) {
            if (str.equals(target)) {
                count++;
            }
        }

        System.out.println("There are " + count + " strings that are the same as \"" + target + "\".");
    }
}

输出结果为：

There are 2 strings that are the same as "string".
