Convert array to list and you can get position of an element. List<String> abcd = Arrays.asList(yourArray);inti=abcd.indexOf("abcd"); Other solution, you can iterator array: intposition=0;for(String obj : yourArray) {if(obj.equals("abcd") {returnposition; } position +=1; }//OR...
可以通过切片操作来实现: # 只保留第一个元素first_element=elements[0] 1. 2. 4. 取第一个元素 最后,我们就可以得到第一个目标元素first_element,可以对其进行后续操作。 三、总结 通过以上步骤,我们可以实现在多个类中找到第一个元素的功能。希望以上内容对你有所帮助,如果有任何疑问或者需要进一步的解释,欢迎...
