我一直在尝试这个,但无法找出下面程序的上述错误

enter code here

import java.util.*;
import java.lang.*;
class mainfunction
{
public static void main(String args[])
{
StringBuffer str;
StringBuffer ptr;
Scanner input=new Scanner(System.in);
int t=input.nextInt();
for(int i=0;i<t;i++)
{
str=new StringBuffer(new StringBuffer(args[i]));
for(int j=0;j<t;j++)
{
for(int k=0;k>t;k++)
{
ptr=str.reverse();
if(str.equals(ptr))
{
break;
}
}
}
}

String prt=str.toString();
System.out.println(prt.length());
System.out.println(prt.charAt(prt.length())/2);
}
}

如何解决问题错误说明:

The local variable str may not have been initialised .please send the appropriate response

最佳答案

如何解决问题错误:局部变量 str 可能尚未初始化

将您的StringBuffer声明为:

StringBuffer str = new StringBuffer();
StringBuffer ptr = new StringBuffer();

通过这样做,您已将 strptr 初始化为其默认值
