几个java的error，找来找去也不觉得是个error，error信息我用注释标出来了，共三行

Question

[code="java"]
import java.util.Scanner;
import java.math.*;
public class Main{
final static int MAXN = 10010;
final static int MAXV = 4;
static int[] value = new int [MAXV];
static int[] vol = new int [MAXV];
static int[] dp = new int [MAXN];[color=red]//Syntax error on token ";", { expected after this token[/color]
value[1]=vol[1]=150;
value[2]=vol[2]=200;
value[3]=vol[3]=350;
public static void main(String[] args){[color=red]//Syntax error on token ")", ; expected[/color]
Scanner in = new Scanner(System.in);
while (in.hasNextInt()) {
int t = in.nextInt();
while ((t--) > 0) {
int n = in.nextInt();
for (int i = 0; i <= n; i++) {
dp[i] = 0;
}
for (int i = 1; i <= MAXV-1; i++) {
for (int j = vol[i]; j <= n;j++) {
dp[j] = Math.max(dp[j], dp[j-vol[i]]+value[i]);
}

}
System.out.println(n-dp[n]);
}
}
}
}[color=red]//Syntax error, insert "}" to complete ClassBody[/color]
[/code]

Answer 1

value[1]=vol[1]=150;

value[2]=vol[2]=200;

value[3]=vol[3]=350;

这一段赋值放在方法内，或者用一个static块；
最后多了一个大括号；
[code="java"]
import java.util.Scanner;
import java.math.*;
public class Main{
final static int MAXN = 10010;
final static int MAXV = 4;
static int[] value = new int [MAXV];
static int[] vol = new int [MAXV];
static int[] dp = new int[MAXN];//Syntax error on token ";", { expected after this token[/color]

    public static void main(String[] args){//Syntax error on token ")", ; expected[/color]
        value[1]=vol[1]=150;
        value[2]=vol[2]=200;
        value[3]=vol[3]=350;
        Scanner in = new Scanner(System.in);
        while (in.hasNextInt()) { 
            int t = in.nextInt();
            while ((t--) > 0) {
                int n = in.nextInt();
                for (int i = 0; i <= n; i++) {
                    dp[i] = 0;
                }
                for (int i = 1; i <= MAXV-1; i++) {
                    for (int j = vol[i]; j <= n;j++) {
                        dp[j] = Math.max(dp[j], dp[j-vol[i]]+value[i]);
                    }                   
                }
                System.out.println(n-dp[n]);
            }
        }
    }
}//Syntax error, insert "}" to complete ClassBody[/color]
