由于main方法/java类文件异常而导致我的程序无法运行 [英] My program won't run due to error with the main method/java class file exception
问题描述
我试图找出选择排序算法并通过打印每行来理解它,但是当我运行它时,控制台甚至都不会弹出.我知道我的错误与未找到主类异常和主字符串args方法有关系,但是我不知道如何解决该问题以查看输出.
I am trying to figure out the selection sort algorithm and understand it by printing out each line, but when I run it, the console won't even pop up. I know my error has to do something with the main class exception not found and the main string args method but I don't know how to fix it to see the output.
package sort;
public class Sorting {
private int[] a = new int[]{ 11, 9, 17, 5, 12 };
public Sorting(int[]a) {
this.a = a;
}
public static void main(String[] args) {
}
public void sortInSpace(int[]a) {
for(int startOfUnsorted = 0; startOfUnsorted<a.length; startOfUnsorted++) {
int smallestInUnsorted = Integer.MAX_VALUE;
System.out.println(smallestInUnsorted);
}
}
}
推荐答案
排序"中的主要功能为空,因此如果您尝试运行该类,它将不会打印任何内容.
Your main function in Sorting is empty so it won't print anything if you try to run that class.
public static void main(String[] args) {
}
相反,我将执行以下操作-
Instead I would do the following -
public class Sorting {
private int[] a;
public Sorting(int[]a) {
this.a = a;
}
public void sortInSpace(int[]a) {
for(int startOfUnsorted = 0; startOfUnsorted<a.length; startOfUnsorted++)
{
int smallestInUnsorted = Integer.MAX_VALUE;
System.out.println(smallestInUnsorted);
}
}
}
创建另一个类,该类将初始化一个Sorting对象类型,并使用该对象来调用该方法.
Create another class which will initiate an object type of Sorting and use the object to call the method.
public static void main(String [] args)
{
int[] a = new int[]{ 11, 9, 17, 5, 12 };
Sorting sortObj = new Sorting(a);
sortObj.sortInSpace(a);
}
输出-

2147483647
2147483647
2147483647
