如下代码 出现类转换异常 怎么解决

[七夜萌萌哒]

public static void main(String[] args) {
String pm ="农展馆=423,东四=378,农展馆=777，东四=888";
Map<String,Integer> map =new HashMap<String,Integer>();
String[]arr =pm.split("[,=]");
for(int i=0;i<arr.length;i+=2){
if(!map.containsKey(arr[i])||Integer.parseInt(arr[i+1])>map.get(arr[i])){
map.put(arr[i],Integer.parseInt(arr[i]));
}
}
System.out.println(map);
}

String pm = "农展馆=423,东四=378,农展馆=777,东四=888";
		Map<String, Integer> map = new HashMap<String, Integer>();
		String[] arr = pm.split("[,=]");		
		for (int i = 0; i < arr.length; i += 2) {
			if (!map.containsKey(arr[i]) || Integer.parseInt(arr[i + 1]) > map.get(arr[i])) {
				map.put(arr[i], Integer.parseInt(arr[i+1]));
			}
		}
		System.out.println(map);
