Java Data Type - 如何将Java String转换为浮点对象

public class Main {

  public static void main(String[] args) {
    Float fObj1 = new Float("10.64");
    System.out.println(fObj1);

    Float fObj2 = Float.valueOf("10.76");
    System.out.println(fObj2);

    float f = Float.parseFloat("7.39");
    System.out.println(f);
  }
}
