好吧，var AwesomeProject = React.createClass({
getInitialState: function() {
return {
isLoading: true,
photos: this.props.photos
};
},
componentWillMount: function(){
fetch("http://localhost:3000/api/photos/", {
method: "GET",
headers: {
"x-access-token":"xxxxx",
"x-key":"xxxx"
},
})
.then((response) => response.json())
.then((responseData) => {
AlertIOS.alert(
"GET Response",
"Search Query -> " + JSON.stringify(responseData)
)
// Set both state properties at the same time to avoid passing an undefined value as a prop to RenderPhotos
this.setState({
isLoading: false,
photos: JSON.stringify(responseData)
});
})
.done();
},
render: function() {
if(this.state.isLoading){
return <View><Text>Loading...</Text></View>
}
// RenderPhotos should receive this.state.photos as a prop, not this.props.photos
return (
<RenderPhotos photos={this.state.photos}/>
);
},
});
var RenderPhotos = React.createClass({
getInitialState: function() {
return {
photos: this.props.photos
};
},
render: function(){
var photos = Photos;
return (
<View>
<Text> {this.props.photos[0]} </Text>
</View>
)
}
});
会给你freq[7]，因为你的数组只有7个元素，索引从0到6。
除此之外，将数组元素作为单独的参数传递给ArrayIndexOutOfBoundsException方法是没有意义的。只需在一个参数中传递整个数组。
答案 1 :(得分：1)
您有java.lang.ArrayIndexOutOfBoundsException这意味着您尝试从索引中获取大于数组大小的元素。
所以，使用
int comparison=max(freq[0],freq[1],freq[2],freq[3],freq[4],freq[5],freq[6]);
而不是
int comparison=max(freq[1],freq[2],freq[3],freq[4],freq[5],freq[6],freq[7]);
因为JAVA索引从 0 开始而不是 1 ！

请为您的帖子提问，而不仅仅是空方法。下面的代码可用于查找max：
