int []b=new int[10];
int i=0,j=0;
for(j=0;j<10;i++,j++){
if(j<=4)
b[j]=a[i+5];
else
b[j]=a[i-5];
}
for(i=0;i<10;i++){
System.out.print(a[i]+" ");
}
System.out.println();

int [] fArray=new int[10];
//...init your fArray;
int temp;
int i=0;
int j=10;
for(i=0;i<5;i++){
temp=fArray[i];
fArray[i]=fArray[i+5];
fArray[i+5]=temp;
}
for(i=0,j=i+5;i<10;i++){
System.out.println("the first items is "+fArray[i]+", and the end items is "+fArray[j+5]);
if(i>5){
j=i-5;
}
}

----------------------------------------------------
int [] fArray=new int[10];
for(int i=0,j=10;i<10;i++,j--){
System.out.println("items is "+fArray[i]+" and changed items is "+fArray[j]");
}
