String[] cars = {"Volvo", "Bmw", "Ford", "Manza"}

 

int [] score = new int [10]

Access the Element of an Array

String cars = {"Volvo", "BMW", "Ford", "Mazda"};
System.out.println(cars[0]); //Output Volvo

Array Length

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
System.out.println(cars.length); //Outputs 4

배열의 출력

for(int i = 0; i < 10; i ++)

  System.out.println(score[i]);

배열의 복사

int tmp[] = new tmp[10];
for(int i = 0; i < 10; i ++){
	temp[i] = score[i];
}
