//1.一维数组的定义
int [] a = {1,2,3,4,5,6};//直接定义且赋值
int [] b = new int [6]; //只定义数组不赋值
int [] c = new int []{1,2,3,4,5,6}; //初始化且赋值
//2.获取数组长度
//System.out.println(a.length);//获取数组的长度
//（数组命名）.（长度）
//3.取出数组中元素的值
//3.1通过下标单独去取值
System.out.println(a[0]);
System.out.println(a[5]);
System.out.println(a[a.length-1]);
//3.2通过for循环逐个取值
for (int i = 0; i < a.length; i++) {
System.out.println(a[i]);
}
//4.给数组中的元素赋值
//4.1单个赋值
b[0] = 98;
b[1] = 96;
b[2] = 94;
b[3] = 92;
b[4] = 90;
b[5] = 88;
for (int i = 0; i < b.length; i++) {
System.out.println(b[i]);
}
//4.2通过for循环全部赋值
for (int i = 0; i < 6; i++) {
b[i]=i;
}
for (int i = 0; i < b.length; i++) {
System.out.println(b[i]);
}
