java实现坐标数组拆分拆分

public  static  String getloglat(String ){
	String  p= "121.234952,31.024395,121.236937,31.024321,121.23683,31.022106,121.235092,31.021683,121.235017,31.023062,121.236905,31.023347";
	String []  loglat = p.split(",");
	String log ="";
	String lat ="";
	for (int j = 1; j <loglat.length ; j=j+2) {
		log+=loglat[j]+",";
	}
	for (int j = 0; j <loglat.length ; j=j+2) {
		lat+=loglat[j]+",";
	}
	System.out.println(log);
	System.out.println(lat);
	return log+"|"+lat;
}
