编写一个Java程序，从键盘输入两个字符序列，第一个字符序列给string1,第二个字符序列给string2,

public class test {
public static void main(String[] args) {
String string1=args[0];
String string2=args[1];
boolean boo=string1.indexOf(string2)!=-1
System.out.println(boo);
}
}

import java.io.*;

public class StringTest {

public static String inputString(){
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
String str=null;
try{
str=br.readLine();
}catch(IOException e){

}
return str;
}

public static void main(String []args){
String string1=null,string2=null;
System.out.print("Input the first string1 :");
string1=StringTest.inputString();
System.out.print("Input the second string2 :");
string2=StringTest.inputString();
if(string1.indexOf(string2)!=-1)
System.out.println(string2+" exists in "+string1);
else
