Question

JAVA生成25个int类型的随机数,对每个随机值,将其分类为大于、小于、等于紧随它生成的值

import java.util.Random;
public class Third_one {
public static void main(String args[]){

for(int i = 1; i <= 25;i++){
int a = (new Random()).nextInt(100);
int b = 0;
if(i==1){
System.out.print(a+ " ");
}
else{
if(b==a)
System.out.print("="+a+" ");
else if(b<a)
System.out.print("<"+a+" ");
else
System.out.print(">"+a+" ");
}

b = a;

}
}
}

我写的到底哪里有问题？

LZ这么写不好啊，其实用个数组就解决这个问题了：
import java.util.Random;
public class Test3 {
public static void main(String args[]) {
int [] arr = new int[25];
for (int i = 0; i < arr.length; i++) {
arr[i]=(new Random()).nextInt(100);
}
String s = "";
for (int i=0;i<arr.length;i++) {
if (i!=arr.length -1 ) {
if (arr[i] < arr[i+1]) {
s = " < ";
}
else if (arr[i] > arr[i+1]) {
s = " > ";
}
else {
s = " = ";
}
if (i == 0)
System.out.print(arr[i]+s+arr[i+1]);
else
System.out.print(s+arr[i+1]);
}
}
}
}
