Java 数组将输入与数组匹配

Question

我正在尝试在类中编写一个方法，提示用户输入学生的姓名。然后在现有名称列表中搜索匹配项。但我似乎无法弄清楚如何继续编码以搜索有效的匹配项。

 public void modifyExam(String [] names)
 {
 String name;
 Scanner scanner = new Scanner(System.in);
 System.out.println("Please enter the name of the student whose grade you would like to modify: ");
 name = scanner.nextLine();
 boolean nameMatch = true;
      for (int i=0; i<names.length; i++) 
      {
       // ....
      }

Answer 1

您应该使用 .equals() 来比较 Java 中的字符串。示例:

public void modifyExam(String [] names) {
    String name;
    Scanner scanner = new Scanner(System.in);
    System.out.println("Please enter the name of the student whose grade you would like to modify: ");
    name = scanner.nextLine();
    boolean nameMatch = false;
    for (int i=0; i<names.length; i++) {
        if( names[i].equals(name) ) {
            // do your logic here ...
        }
    }
}
