如何尽可能优化此功能

public void r1(String st1, int[] ar1) {
    String inox = "newsearch";
    for (int j = 0; j < ar1.length; j++) {
        if (st1.equals(inox) && ar1[j] * 2 > 20) {
            Integer intx = new Integer(ar1[j]);
            intx = intx * 2;
            System.out.print(intx.toString());
        }
    }
}

这是相当奇怪的代码,但它是相同的.

public void r1(String st1, int[] ar1) {
    if (!str1.equals("newsearch")) return;

    for (int j : ar1) {
        int j2 = j * 2;
        if (j2 > 20) 
            System.out.print(j2);
    }
}
