[英]Passing a value/values outside of for loop to a variable - java :: processing
I am looking how to pass the value word and its corresponding count to be saved into a variable outside the for
loop. 我正在寻找如何将值字及其相应的计数传递给
for
循环外的变量。 My code is currently: 我的代码目前是:
import java.util.Iterator;
import java.util.*;
import com.google.common.collect.ImmutableMultiset;
import com.google.common.collect.Multiset;
import com.google.common.collect.Multisets;
ImmutableMultiset<String> top = null;
void setup() {
size(800, 480);
smooth();
String[] data = loadStrings("data/data.txt");
ImmutableMultiset<String> myMultiset = ImmutableMultiset.copyOf(data);
top = Multisets.copyHighestCountFirst(myMultiset);
Iterator it = top.entrySet().iterator();
for (int i = 0; (i < 5) && it.hasNext(); i++) {
Multiset.Entry entry = (Multiset.Entry) it.next();
String word = (String) entry.getElement();
int count = entry.getCount();
System.out.println(word + " -> " + count);
}
}
I need these values to apply them to a bar chart in my draw()
function. 我需要这些值将它们应用到我的
draw()
函数中的条形图。
You can declare the variables in your class and not locally in your enhanced loop. 您可以在类中声明变量,而不是在增强循环中本地声明。
eg 例如
private String word;
private int count;
and use getters to call them 并使用getter来调用它们
eg 例如
public String getWord(){ return word; }
To expand on Murat's answer, this is a matter of variable scoping. 为了扩展穆拉特的答案,这是一个变量范围问题。 Anything declared within the for loop block (between the {} bounds) will only be visible within this block.
在for循环块中(在{}边界之间)声明的任何内容将仅在此块中可见。
If you declare the count variable outside the for loop block, you will be able to use it within the scope of the block that contains the for loop; 如果在for循环块之外声明count变量,则可以在包含for循环的块的范围内使用它; in this case the setup method.
在这种情况下是设置方法。
Murat's example will allow you to obtain the value of this variable from anywhere, whether it's within this or some other class. Murat的例子允许您从任何地方获取此变量的值,无论是在此类还是其他类中。
