split()函數和trim()函數的使用方法

本文地址: http://blog.csdn.net/caroline_wendy/article/details/24465141

詳細參考Java API: http://docs.oracle.com/javase/6/docs/api/java/lang/String.html

split()函數是依據參數如",", "-", " "等, 切割String字符串, 返回一個String的數組(String[]), 能夠通過索引指定元素.

假設未找到, 則返回整個String字符串, 作為String數組(String[])的第0個元素.

trim()函數

代碼:

public class Split {
	
	public static void split() {
		String details = "M 2.9 - 9km W of Alberto Oviedo Mota, Mexico"; 
		String magnitudeString = details.split(" ")[1];
		System.out.println(magnitudeString);
		details = details.split(",")[1].trim();
		System.out.println(details);
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		split();
	}

}
