   {
    int testscore=97;
    char grade;
    if(testscore>=90)
    grade=A
    else if(testscore>=80)
    grade=B
    else if(testscore>=70)
    grade=C
    else if(testscore>=60)

  }

Answer 1

public static void main(string args[])
"[]"的位置好像有点问题?

Answer 2

public class test
{
public static void main(String args[])
{
int testscore=97;
char grade;
if(testscore>=90)
grade='A';
else if(testscore>=80)
grade='B';
else if(testscore>=70)
grade='C';
else if(testscore>=60)
grade='D';
else
grade='E';
System.out.println(""+testscore+ " is  "+grade);
}
}你的错误太多了  好好学习把

Answer 3

class scorelevel
{
public static void main(String args[])
{
    int testscore=97;
    char grade;
    if(testscore>=90)
     grade='A';
    else if(testscore>=80)
     grade='B';
    else if(testscore>=70)
     grade='C';
    else if(testscore>=60)
     grade='D';
    else
     grade='E';
     System.out.println(testscore+"  is   "+grade+"\n");
     }
}

Answer 4

错误太多了；
class Ch
{
   public static void main(String args[])
   {
    int testscore=97;
    char grade;
    if(testscore>=90)
    grade='A';
    else if(testscore>=80)
    grade='B';
    else if(testscore>=70)
    grade='C';
    else if(testscore>=60)
    grade='D';
       else
          grade='E';
    System.out.println(testscore+"is"+grade+"\n");
     }
  }
就可以了。注意中英文切换和大小写。

Answer 5

强烈建议lz，加一个输入语句，然后使用switch进行选择

Answer 6

严重同意楼上的.这种小练习肯定是用 Switch实现比较好.

Answer 7

class scorelevel{
   public static void main(String args[]){
    int testscore=97;
    char grade;
    if(testscore>=90)
     grade='A';
    else if(testscore>=80)
     grade='B';
    else if(testscore>=70)
     grade='C';
    else if(testscore>=60)
     grade='D';
    else
          grade='E';
    System.out.println(testscore+grade);
     }
