package ss;

public class a15 {
    public static boolean isSorted(int table[])
    {
        int i;
        
        
        for(i=0;i<table.length-1;i++)
        {
            if(table[i]>table[i+1])
               
            
                return false;
            break;
                 
            
               
        }
        
        return  true;
   
    }
   
public static void main(String[] args)
{
    int table[]={1,2,5,4,5};
   
    System.out.println(isSorted(table));
}
}

这个结果居然是对的

你那个比较数组会越界吧
我贴一下我的代码
public class Test {
    public static String isSorted(int table[])
    {
        int i;
        int count1=0;
        int count2=0;
        

        for(i=0;i<table.length-1;i++)
        {
            if(table[i]>table[i+1]){
                count1++;
            }else if(table[i]<table[i+1]){
                count2++;
            }
               
        }
        if(count1==table.length-1||count2==table.length-1){
            return "The number is sorted";
        }else{
            return "The number is not sorted";
        }
        
        
        
        
    }
   
public static void main(String[] args)
{
    int table[]={1,7,4,5};
    System.out.println(isSorted(table));
    for(int j=0;j<table.length;j++){
        System.out.println(table[j]);
    }
   
}
}

你把执行的结果贴出来
