数组练习

//此次只为理解程序和练习敲代码

//本程序创建一个整数类型
public class ArrayDemo {
public static void main(String args[])
{
int[]anArray;
anArray=new int[3];
anArray[0]=100;
anArray[1]=200;
anArray[2]=300;
System.out.println("Element at indx0:"+anArray[0]);
System.out.println("Element at indx1:"+anArray[1]);
System.out.println("Element at indx2:"+anArray[2]);
}

}

//二维数组的用法

public class MultiDimArrayDemo {public static void main(String args[]){Sting[][]names = {{"Mr.","Mr.","Mr."},"Smith","Jonrs"}};System.out.println(names[0][0] = names[1][0]);//Mr.SmithSystem.out.println(names[0][2] = names[1][1]);//Mr.Jones}}
