messagetool.java

一段很有意义的源码,看了就知道,不信试一试啊!

package com.sofmit.tools;

public class MessageTool {
	
	/***
	 * 返回Long型数组;
	 * @param testStr
	 * @return
	 */
	public long[] StringToLongArray(String testStr){
		String[] testStr_b = testStr.split(","); 
		 long a[] = new long[testStr_b.length];
		 for(int i=0;i<testStr_b.length;i++)
			{
				a[i] = Long.parseLong(testStr_b[i]);
			}		
		return a;		
	}
	
	/***
	 * 返回&nbsp;字符
	 * nv 字符串
	 */ 
	  public static String changeNull(String nv) {
	    if (nv != ""&&nv.length()>0) {
	      return nv;
	    }
	    else {
	      return "&nbsp;";
	    }
	  }
	  
	  public static String changeNullto(String nv) {
		    if (!nv.equals("null")) {
		      return nv;
		    }
		    else {
		      return "";		      
		    }
		  }
}
