float数组java

‘壹’ java 中string 数组怎样转化为float数组

String a[]={"1","2","3","44","76"};
float b[]=new float[a.length];
for(int i=0;i<a.length;i++)
b[i]=Float.parseFloat(a[i]);

‘贰’ Java float数组 去重复数字

import java.util.*;
public class Test{
public static void main(String args[]){
float f[] = {15.52f , 15.52f , 16.12f , 17.4f , 19.2f , 19.2f , 18.3f};
Set set = new TreeSet();
for(int i = 0; i < f.length;i ++){
if(!set.add(f[i])){
set.remove(f[i]);
}
}
Iterator it = set.iterator();
while(it.hasNext()){
System.out.println(it.next());
}
}
}

‘叁’ java中如何初始定义一个数组是float型的

float foo[]=new float[n];n为该数组的长度。一维数组的初始化?，例：float foo={1,2,3,4,5};
