the usage of String.trim()

下面的示例演示使用的java.lang.String.trim()方法

package com.yiibai;

import java.lang.*;

public class StringDemo {

  public static void main(String[] args) {
  
    // string with leading and trailing white space
    String str = " This is YiiBai ";
    
    System.out.print("Before trim = ");
    System.out.println(".." + str + "..");
    
    // leading and trailing white space removed
    System.out.print("After trim = ");
    System.out.println(".." + str.trim() + "..");
  }
}

让我们来编译和运行上面的程序，这将产生以下结果：

Before trim = .. This is YiiBai ..
After trim = ..This is YiiBai..
