数据去零操作

源程序：

public class Test{

public static void main(String[] args){

int oldArr[] = {1 , 3 , 8 , 0 , 0 , 6 , 6 , 0 , 5 , 4 , 7 , 6, 7 , 0 , 5} ;

int newArr[] = null ;

newArr = new int[oldArr.length] ;

int j = 0 ;

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

if(oldArr[i] != 0){

newArr[j] = oldArr[i] ;

j++ ;

}

}

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

System.out.print(oldArr[i] + "  ") ;

}

System.out.println() ;

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

if(newArr[i] != 0){

System.out.print(newArr[i] + "  ") ;

}

}

}

}
