split()函数和trim()函数的使用方法

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

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

split()函数是依据參数如",", "-", " "等, 切割String字符串, 返回一个String的数组(String[]),

能够通过索引指定元素.

假设未找到, 则返回整个String字符串, 作为String数组(String[])的第0个元素.

trim()函数是去掉String字符串的首尾空格;

代码:

/**

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();

}

}

输出:

2.9
