Creating a Corresponding Array to a char Array in JAVA

If

char [] a = {'x','y','x'};

I need an

int [] b={5,3,5};

It is clear that 'x' correspond to 5 and 'y' corresponds to 3.

I tried to get this way through JAVA code:

public static void main(String[] args) {


    char [] a= {'x','y','x'};
    int[] b ={};

    for(int i=0; i<a.length; i++){
    if( a[i]=='x'){
        b[i]=3;
    } else {
        b[i]=5;
    }

    System.out.println(b[i]);
    }

    }}

but failed. I need help.

Define the b array like:

int[] b = new int[a.length];

And also, since you want x to correspond to 5, you have to do:

if(a[i] == 'x') {
    b[i] = 5;
} else {
    b[i] = 3;
}
