Android 将一个数组复制到另一个数组,android,Android,我有两个数组，第一个是optionlist，它是这样的，由json填充 public class Options { private String age; private String optionNo; private String installmentAmount; private String noInstallment; public String getNoInstallment() { return noInstallme

我有两个数组，第一个是optionlist，它是这样的，由json填充

public class Options {
    private String age;
    private String optionNo;
    private String installmentAmount;
    private String noInstallment;

    public String getNoInstallment() {
        return noInstallment;
    }

    public void setNoInstallment(String noInstallment) {
        this.noInstallment = noInstallment;
    }

    public String getInstallmentAmount() {
        return installmentAmount;
    }

    public void setInstallmentAmount(String installmentAmount) {
        this.installmentAmount = installmentAmount;
    }

    public String getOptionNo() {
        return optionNo;
    }

    public void setOptionNo(String optionNo) {
        this.optionNo = optionNo;
    }



second one is templst 




public class TempList {
private String tage;
private String toptionNo;
private int tinstallmentAmount;
private int tnoInstallment;
private String tdescription;
private String tto;
private String tmode;
private String tfrom;

public String getTage() {
    return tage;
}
public void setTage(String tage) {
    this.tage = tage;
}
public String getToptionNo() {
    return toptionNo;
}
public void setToptionNo(String toptionNo) {
    this.toptionNo = toptionNo;
}
public int getTinstallmentAmount() {
    return tinstallmentAmount;
}
public void setTinstallmentAmount(int tinstallmentAmount) {
    this.tinstallmentAmount = tinstallmentAmount;
}
public int getTnoInstallment() {
    return tnoInstallment;
}
public void setTnoInstallment(int tnoInstallment) {
    this.tnoInstallment = tnoInstallment;
}
public String getTdescription() {
    return tdescription;
}
public void setTdescription(String tdescription) {
    this.tdescription = tdescription;
}
public String getTto() {
    return tto;
}
public void setTto(String tto) {
    this.tto = tto;
}
public String getTmode() {
    return tmode;
}
public void setTmode(String tmode) {
    this.tmode = tmode;
}
public String getTfrom() {
    return tfrom;
}
public void setTfrom(String tfrom) {
    this.tfrom = tfrom;
}

}
在我的主要活动中，当用户输入年龄时，我想将一些详细信息复制到模板中这是我的代码

int age=18;          
int amount = 10000;  
int installamt;
int tempIndx=0; 



for(int i=0; i < optionlst.length; i++){
        if (age == Integer.parseInt(optionlst[i].getAge()))
        {
            installamt =  (amount/10000)*(Integer.parseInt(optionlst[i].getInstallmentAmount()));
            templst[tempIndx].setTinstallmentAmount(installamt);
                 templst[tempIndx].setTnoInstallment(Integer.parseInt(optionlst[i].getNoInstallment()));
            tempIndx++ ;    
        }
