java数组---数组的使用(打印,求和,最大值)


public static void main(String[] args) {

int[] arrays={1,2,3,4,5}; //打印该数组

for (int i = 0; i < arrays.length; i++) {

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

}
System.out.println("========================");

int sum=0; //求他们的和
for (int i = 0; i < arrays.length; i++) {
sum=sum+arrays[i];

}System.out.println(sum);
System.out.println("========================");

int max=arrays[0]; //求最大值

for (int i = 0; i < arrays.length; i++) {
if (arrays[i]>max){
max=arrays[i];
}
}
System.out.println(max);
}
