eclipse处理长字符串拼接快捷方法类

你在后台写sql文访问数据库时是不是要这样写

String sql="select a,"

                 +"b,"

                 +"c "

                 +"from table";

当sql语句短还好，要是长了该写多少个“+”和““”啊，于是就想写一个工具类处理长字符串拼接的问题

import java.util.ArrayList;

import java.util.Scanner;

public class GenSqlString {

	/**

	 * 处理长字符串拼接

	 * @param args

	 */

	public static void main(String[] args) {

		ArrayList<String> array = new ArrayList<String>();

    	Scanner scn = new Scanner(System.in);

    	String line;

    	String reString;

    	System.out.println("请输入您的长字符串");

    	//BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

    	//String reString="+\""+br.readLine()+" \"";

    	/** 当输入end时回车结束*/

    	while (!"end".equals(line = scn.nextLine())) {

			array.add(line);

		}

    	System.out.println("The result is: \r\n");

    	int i=1;

    	for(String str : array){

    		if(i==1){

    			reString="\""+str+" \"";

    		}else if(i==array.size()){

    		    reString="+\""+str+" \";";

    		}else{

    			reString="+\""+str+" \"";

    		}

			System.out.println(reString);

			i++;

		}

	}

}

虽然简单点，但是能用就行，提高开发效率嘛
