 {

public static void main(String[] args)

 {

 Float fObj = new Float("10.50");

byte b = fObj.byteValue();

System.out.println(b);

short s = fObj.shortValue();

System.out.println(s);

int i = fObj.intValue();

System.out.println(i);

float f = fObj.floatValue();

System.out.println(f);

double d = fObj.doubleValue();

System.out.println(d);

  }

}

Convert Java String to Float Object
