Question

java数组的赋值及使用

怎么声明数组？怎么使用？

Answer 1

Object[] array = new Object[ int size ];/Object array[] = new Object[ int size ];size 是数组大小
eg: String[] str = new String[ 10 ];
str[ 0 ] = "1"; str[ 1 ] = "1";

Object[] array = {obj1,obj2,==};/Object array[] = {obj1,obj2,==};

Object[] array = new Object[]{obj1,obj2,==};/Object array[] = new Object[]{obj1,obj2,==};

遍历：
for(int i = 0;i < array.length;i++){
System.out.println( array[ i ] );
}

或者
for(Object obj : array){
System.out.println( obj );
}
