.将一个数组中值=0的项去掉,将不为0的值存入一个新的数组,比如: int a[]={1,3,4,5,0,0,6,6,0,5,4,7,6,7,0,5}; 生成的新数组为: int b[]={1,3,4

package com.shuzu;

public class Test_1 {

/**
* int a[]={1,3,4,5,0,0,6,6,0,5,4,7,6,7,0,5}; 生成的新数组为: int
* b[]={1,3,4,5,6,6,5,4,7,6,7,5}

public static void main(String[] args) {
// TODO Auto-generated method stub
int a[] = { 1, 3, 4, 5, 0, 0, 6, 6, 0, 5, 4, 7, 6, 7, 0, 5 };
int j = 0;
for (int i = 0; i < a.length; i++) {
if (a[i] != 0) {
j++;//记录不为0的个数
}
}
int []b = new int[j];//定义一个数组，长度为j，就是不为0的个数
j = 0;
for(int i = 0; i < a.length; i++){
if(a[i] != 0){
b[j] = a[i];//不为0的数字装入新的数组
j++;
}
}
for(int c:b){
System.out.print(c+" ");
}
System.out.println();
}
