的java：创建字符串

Question

我开始用java和我在寻找如何创建一个字符串数组二维矩阵： 我二维数组包含应：

10 20 "OK" 
5 30 "KO" 
20 100 "NA" 
10 60 "OK" 

String[][] matrix = new String[i][j]; 
for(r=0;i<matrix.length; r++) { 
for (int c=0; c<matrix [r].length; c++) { 
    System.out.print("10 " + matrix [r][c]); 
} 

Answer 1

弗洛林说了什么，但是用简化的for循环：

String [][] matrix = { {"10","20","OK"}, {"5","30","KO"}, {"20","100","NA"}, {"10","60","OK"} }; 

for (String [] line : matrix) { 
    for (String s: line) { 
     System.out.print ("10 " + s); 
    } 
} 

Answer 2

String[][] matrix = { {"10","20","OK"},{"5","30","KO"}, {"20","100","NA"}, {"10","60","OK"} }; 

Answer 3

一切似乎都不错。也许你可以做一个更好的利用Java中的每个循环：

String[][] matrix = new String[i][j]; 
for(String[] rows : matrix) { 
for (String row : rows) { 
    System.out.println("10 " + row); 
} 

问候， 斯特凡

Answer 4

@Jigar说什么

String[][] matrix = { {"10","20","OK"},{"5","30","KO"}, {"20","100","NA"}, {"10","60","OK"} }; 

加打印：

for(r=0;i<matrix.length; r++) { 
for (int c=0; c<matrix [r].length; c++) { 
    System.out.print(matrix [r][c] + " "); 
} 
System.out.println(); 
}
