java数组基础

java数组基础public class shuzu_fuzhi2 {
public static void main(String[] args){
int[] shuzuA={45,35,57,78,54,55};
int[] shuzuB=new int[shuzuA.length];
for(int i=0;i<shuzuA.length;i++){
shuzuB[i]=shuzuA[i];
shuzuB[i]++;
System.out.println("shuzuA["+i+"]="+shuzuA[i]);
System.out.println("shuzuB["+i+"]="+shuzuB[i]);
}

}

}
为什么输出是从1下标开始。而且每个值都加了一

Answer 1

public static void main(String[] args) {
		//定义数组 初始化长度并赋值
		int[]shuzuA={45,35,57,78,54,55};
		//定义数组并初始化长度
		int[] shuzuB=new int[shuzuA.length];
		//循环shuzuA 数组
		for(int i=0;i<shuzuA.length;i++){
			//将A 数组的值 赋给B
		shuzuB[i]=shuzuA[i];
		//B数组的值加+   注意 shuzuB[i]是取值  ++是自增1 也就是当前i的坐标值+1
		//相当于  int b= shuzuB[i]+1;  shuzuB[i]=b;
		shuzuB[i]++;
		System.out.println("shuzuA["+i+"]="+shuzuA[i]);
		System.out.println("shuzuB["+i+"]="+shuzuB[i]);
		}
		
		}

下标从0开始了啊。。你有自增啊不就+1咯
