Java - Skip values in for loop

I am trying to skip values using a for loop. Something like

for(int i = 32; i <= 255 - but skip 128 to 159; i++) {

    char ascii = (char) i;
    System.out.println(ascii);

}

Any suggestions? Thanks!

You can try this:

for (int i=32; counter<=255; i++){
    if (counter>=128 && counter<=159) {
    continue;
    }
char ascii = (char) i;
System.out.println(ascii);
}

Here is some code:

public static void main(String[] args) {
    for(int i = 32; i <= 255; i++) {
        if (i < 128 || i > 159) {
            char ascii = (char) i;
            System.out.println(ascii);
        }
    }
}

just for completeness, this is also possible

for (int i = 32; i <= 255; i = (i == 127 ? 160 : i + 1)) {
    char ascii = (char) i;
    System.out.println(ascii);
}

Or add the test to the loop like a functional language:

for(int i = 32; i <= 255; i++) if (i < 128 || i > 159) {
    char ascii = (char) i;
    System.out.println(ascii);
}

Use this at the beginning of your loop:

for(int i = 32; i < 256; i++) {
    if(i == 128) i = 160;
    //...
}

This is MUCH better than simply continuing. You don't want to iterate over 128 to 159; you'd be wasting time.

I would make two loops :

    int MIN = 128;
    int MAX = 159;

    for(int i = 32; i < MIN ; i++) {

    char ascii = (char) i;
    System.out.println(ascii);
}

    for(int i = MAX + 1; i < 255; i++){
     char ascii = (char) i;
    System.out.println(ascii); 
    }

        i = 160;
    }

You could add an if statement inside your loop.-

for(int i = 32; i <= 255; i++) {
    if (i < 128 || i > 159) {
        char ascii = (char) i;
        System.out.println(ascii);
    }
}

You can skip the elements that you do not want, like this:

for(int i = 32; i <= 255; i++) {
    if (i >= 128 && i <= 159) continue;
    char ascii = (char) i;
    System.out.println(ascii);
}

or split the loop in two, like this:

for(int i = 32; i <= 127; i++) {
    char ascii = (char) i;
    System.out.println(ascii);
}
for(int i = 160; i <= 256; i++) {
    char ascii = (char) i;
    System.out.println(ascii);
}
