java将一个int和string数组合并到第三个数组中
There are 2 arrays, one of int and one of Strings (words) ; sort both of them and then print it in a way that at odd places it should be words and at even numbers.
这是我的代码:
import java.util.*;
public class JavaApplication4 {
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
int num[]=new int[10];
String str[]=new String[10];
String str1[]=new String[20];
for(int i=0; i<5; i++)//for taking strings
{
str[i]=in.next();
}
for(int i=0; i<5; i++)//for taking nums
{
num[i]=in.nextInt();
}
for(int i=0; i<5; i++)
{
System.out.println("The String are "+str[i]);
}
for(int i=0; i<5; i++)
{
System.out.println("The num are "+num[i]);
}
for (int i = 0; i < 5; i++) //for sorting nums
{
for (int j = i + 1; j < 5; j++)
{
if (num[i]>(num[j]))
{
int temp = num[i];
num[i] = num[j];
num[j] = temp;
}
}
}
for (int i = 0; i < 5; i++)// for sorting strs
{
for (int j = i + 1; j < 5; j++)
{
if (str[i].compareTo(str[j])>0)
{
String temp = str[i];
str[i] = str[j];
str[j] = temp;
}
}
}
System.out.println("The sorted strings are:");
for(int i=0; i<10; i++)//for merging both
{
if((i+1)%2==0)
{
int k=0;
str1[i]=String.valueOf(num[k]);
System.out.println("The String are "+str1[i]);
k++;
}
else
{
int j=0;
str1[i]=str[j];
System.out.println("The String are "+str1[i]);
j++;
}
}
/* for(int i=0; i<10; i++)
{
System.out.println("The String are "+str1[i]);
}
*/
}
}
我得到的输出是:
The sorted strings are:
The String are ab
The String are 1
The String are ab
The String are 1
The String are ab
The String are 1
The String are ab
The String are 1
The String are ab
The String are 1
它只取两个数组的第一个元素
# 1 楼答案
应该在循环之前,而不是在循环内部,将
k
和j
初始化为0
# 2 楼答案
其他人指出了根本原因。除此之外,为什么要用容量10(和20)初始化数组}{},这是所需容量5(和10)的两倍
num[]
{另一个问题是
str1[]
的名字非常糟糕# 3 楼答案
您可以使用
Arrays
类对数组进行排序同样,尝试使用第二个数组
现在,通过添加两个数组的大小来声明另一个数组:
