一维数组的创建方法
//第一种创建array的方法: String[] familyMembers = new String[4]; familyMembers[0] = "jerry"; familyMembers[1] = "elaine"; familyMembers[2] = "george"; familyMembers[3] = "kramer"; //第二种创建array的方法: String[] familyMembers = new String[]{"jerry", "elaine", "george", "kramer"}; //第三种创建array的方法: String[] familyMembers; familyMembers = new String[]{"jerry", "elaine", "george", "kramer"}; //第四种创建array的方法: String[] familyMembers = {"jerry", "elaine", "george", "kramer"}; //初始化必须在同一行 //下面这种不行 String[] familyMembers; familyMembers = {"jerry", "elaine", "george", "kramer"};
访问数组元素,遍历数组
public class Array3 { public static void main(String[] args) { String[] familyMembers = {"jerry", "elaine", "george", "kramer"}; //changing data familyMembers[3] = "newman"; //looping through array for (int i = 0; i < familyMembers.length; i++) { System.out.println(familyMembers[i].toUpperCase()); } // for (String item : familyMembers) // { // System.out.println(item); // } } }
