I am using Java 1.4 for an old project.
I have a string array
String a[0]={"200,300"}
String a[1]={"700,500"}
String a[2]={"900,400"}
as so on,
for this I need to create 2 string array to get the first value in a string array and second value in different string array.
ex:
String a[0]="200"
String a[1]="700"
String a[2]="900"
String b[0]="300"
String b[1]="500"
String b[2]="400"
I am not getting how can I do this.
If the length of the string array is known,
String[] newString = new String [6];
int count = 0;
for(int i = 0; i<3 ; i++){
newString[i] = a[i];
count++;
}
for(int j=0; j<3; j++){
newString[count] = b[j];
count++;
}
EDIT:
Previously i got your question wrong. The following solution will help you. to divide a into 2 string arrays.
String a[] = new String [3];
a[0]={"200,300"};
a[1]={"700,500"};
a[2]={"900,400"};
String[] newStr1 = new String [a.length];
String[] newStr2 = new String [a.length];
for(int i = 0; i<3 ; i++){
String [] x= a[i].split(",");
newStr1[i] = x[0];
newStr2[i] = x[1];
}
{200,300} on splitting this string you get {200 in x[0] to avoid 1st { i used substring()
Looking at your code, this provides you the correct solution,
int n = 3; //This can change as your array size is not known
String a[] = new String [n];
a[0]="200,300";
a[1]="700,500";
a[2]="900,400"; //And So on
String[] b1 = new String [n];
String[] b2 = new String [n];
for(int i = 0; i<n ; i++)
{
String [] numbers= a[i].split(",");
b1[i] = numbers[0];
b2[i] = numbers[1];
}
First you cant defined String array as string a[1]={700,500}. It is wrong way.
And second, Here is what you want :
a[0]=new String[]{"200","300"};
a[1]=new String[]{"700","500"};
a[2]=new String[]{"900","400"};
String x[] = new String[a.length];
String y[] = new String[a.length];
for(int i=0;i<a.length;i++){
x[i] = a[i][0];
y[i] = a[i][1];
}
a like this : String a[][] = new String[3][2];
