线性搜索数组字符串

Question

我需要在我的数组中找到一个字符串元素，但是当我查看时，它总是会被找到，即使不是这样。我想调用一种方法。

    String name = "";
    boolean result = false;




   if (option == 5)
            {
        System.out.println("Please enter a students name");
        name = input.next();

        linearSearch(student);


        if (result = true)
        {System.out.println(name+" found in element ");}

        else
        {System.out.println(name+" not found in element ");}


    }


public static boolean linearSearch(String b[])
{
String key = null;
boolean searchReturn = false;
for(int i = 0; i < b.length; i++)
{
    //if key is found - return position of key i.e. n
    if( b[i] == key)
    searchReturn = true;
}

return searchReturn;

Answer 1

应使用String.equals（str）方法检查字符串相等性。

尝试

for(int i = 0; i < b.length; i++)
     {
        //if key is found - return position of key i.e. n
        if( b[i].equals(name))
        searchReturn = true;
    }

Answer 2

首先你应该致电if(result == true){} //you performing a assignment.
