调用String的equalsIgnoreCase()方法比较
public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); while(sc.hasNextLine()){ String str1 = sc.nextLine(); String str2 = sc.nextLine(); char[] chsArray = str1.toCharArray(); int count = 0; for(int i = 0;i < chsArray.length;i++){ if((chsArray[i]+"").equalsIgnoreCase(str2)){ count++; } } System.out.println(count); } } }
