Java如何从字符串中删除开头和结尾的空格？
package org.nhooo.example.lang;
public class TrimStringExample {
public static void main(String[] args) {
String text = " tattarrattat ";
System.out.println("Original = " + text);
System.out.println("text.length() = " + text.length());
//trim()方法将产生一个新的字符串对象，其前导和
//删除空间时拖尾。
text = text.trim();
System.out.println("Result = " + text);
System.out.println("text.length() = " + text.length());
}
}上面的代码片段的结果：
Original = tattarrattat text.length() = 22 Result = tattarrattat text.length() = 12
